I remembered I still have the epub in Calibre, so here's a sneak peak of like part of chapter 4 of the first book to give you an idea of the world/writing:

Mordecai shook his head. “You don’t even want to know. So anyway, your planet defaulted on claiming Earth as a sovereign entity. You had 50 local years since first contact, and first contact was several thousand years ago. Whenever those pyramid things were built. The Borant Corporation has a huge backlog of worlds to mine, and your time is now.”

My head swam. “So, they’re taking all of our minerals?”

Mordecai nodded. “Sort of. Borant deals in rare elements and the like. What they end up mining will fit on a single transport. I don’t know too much about that part of the process. The elements involved are unimportant. It’s a big universe out there, and there are plenty of places to mine. That’s not why they’re really here. While Borant does make a profit on the mining, the real money is in the game. The dungeon.”

“How?”

“Are you kidding? The Syndicate consists of over three billion independent star systems. Every season, a new Dungeon Crawler World debuts across the net. Quintillions of citizens of the Syndicate become obsessed with the Crawl.”

“Wait, so this is like a TV show? Like Survivor?”

“Oh, I loved that show. And as far as you’re concerned, yes. It’s a show like Survivor. But it’s more a Running Man situation than a Survivor one.”

I leaned back in the chair. I’m on an alien television show. Holy shit.

Bea had always wanted to be on television. She’d tried out for countless reality shows. Me? I’d rather have a hot poker stuck through my eye. I briefly wondered where she was, and if she was alive. Probably not, I decided. It’d been 5 AM in the Bahamas when it had happened, which meant she’d probably been asleep in her hotel. Probably in bed with that asshole. And if by some miracle she had survived, there’s no way she’d have gone into one of those tunnels.

“So are there people watching right now?” I asked, looking around.

Mordecai put his hands together. “I will get to that in a moment. It doesn’t look like anyone else is going to be joining us any time soon, so let’s get the tutorial started.”

Mordecai’s right hand glowed for a moment, and I felt that haptic buzz in my brain. Across the room, Donut hissed and batted at the air.

You have been granted access to the Crawler Menu.

My world blinked, and several items appeared in my vision. A long green bar—a health bar, I realized—appeared in the top right. It pushed the timer down a notch. That blinking folder remained in my top left. A small minimap appeared in the bottom right.

“You just received a notification,” Mordecai said. “That’s called a crawler notification. There are a few different kinds, but that type will only be seen by you. There are also system messages, which everyone sees no matter what floor they’re on. Those may be in different voices. There are also floor-specific notifications, etcetera.”

“I have a blinking box in my top left,” I said.

“Those are game and status change notifications. Probably from your fight outside a few minutes back,” Mordecai said. “Don’t click it yet. We’ll get there. First, I want you to focus on the map on the bottom right. Look right at it, and make sure you’re thinking about looking at it.”

I did as he asked, and the map got bigger, increasing to fill my entire vision. It was a simple blue and gray map showing the hallways and a few random doorways. Most of the area around us wasn’t filled in. It only showed the area we’d walked, pushing out about twenty meters in every direction. A green dot sat in the middle, right in the guild. Two additional dots appeared, a blue one and a white one. I focused on the blue dot, and a note appeared above it:

Crawler Princess Donut.

The white dot read:

Guildmaster Mordecai.

The whole room glowed yellow, and when I focused on it, it read:

Tutorial Guild.

A trio of X’s appeared outside in the hallway. I mentally clicked on one.

Corpse – Level 2 Goblin.

I mentally clicked away, and the whole map shrank back to normal.

“Good, good,” Mordecai said. “So, you’re the green dot, the blue dots will be other crawlers, white dots will be NPCs such as myself, and mobs will be red. There are a few other kinds, but you’ll figure those out along the way. By the way, no other crawlers or mobs can see your menus, but while you’re inside this guild, I can see what’s on your screen. You are already adept at opening and closing, which is good. Now try focusing on the map again. With your mind, pinch it smaller. And then move it across the screen. That way you can customize your HUD.”

It went on like this for a while, him explaining how to open and close menus within my display. I could just think about it, and a whole menu system would pop up, giving me access to several folders. Once I got used to the weirdness of it being in my head, the system was quite intuitive.

The first menu was player stats. Like I mentioned earlier, I’d played a handful of computer and tabletop RPGs over the years, so this section wasn’t too surprising. My stats were:

Strength: 6

Intelligence: 3

Constitution: 5

Dexterity: 5

Charisma: 4

According to Mordecai, I couldn’t directly adjust these stats. Not yet. I received three stat points every time I leveled up, but I couldn’t distribute them until I picked a race and class. And I couldn’t do that until I reached the third floor down. For now, these numbers went up and down on their own based on my inherent, real-life physical and mental attributes. He also added the typical adult human averaged between three and five for each of these first five stats, so my six in strength was good.

I could find items and potions that would either temporarily or permanently adjust these numbers, but for now, there wasn’t much I could do about them.

And here's like a bit further on - like Chapter 16 - when he's building with goblins (and about where I stopped):

“It’s not going to blow up on me, is it? That dozer thing exploded after it hit the wall.”

“That dozer wouldn’t have blown up if you had twisted the relief valve,” the engineer said. He pointed to a pair of identical spigots on the side of the bike. “If it gets too hot, twist that one right there, and it won’t blow. If the pressure is too high, twist the other one. Don’t mix it up, or you make it worse.”

“How will I know if it’s too hot? Or if the pressure is too high? There are no gauges!”

He smiled, revealing a row of sharp teeth.

“Don’t you worry about that, human. You will know. Just listen to the chopper. It will tell you.”

The engineer had pointed at that stack of coal that reached the ceiling, telling me to grab all I could carry. I sneaked around the back of the heap and took a metric fuck-ton of the stuff. I had three piles of 999 coal lumps before the heap started to look noticeably lower.

It was time to jet. Both Rory and Lorelai had disappeared while the goblin engineers worked. They reappeared now. Both of them were blitzed. Rory’s eyes were noticeably slitted, and Lorelai danced seductively toward me as we prepared to leave.

“Wanna have some fun before you go?” Lorelai asked, grasping the front of my tattered jacket. Her breath smelled of rotten fish. She’d removed her bone necklace.

“Uh,” I said.

“Oh, sweetie,” said Donut, “as amusing as I would find it to watch Carl here disappoint yet another woman, we’re on a schedule. Banging monster girls is not the narrative we’re going for with this story. Maybe next time.”

“Sure, but you look me up later, okay?” the goblin said. She reached up and booped me on the nose. “It’d be nice to fuck someone and not have to eat them afterward.” She sighed and turned toward one of the Bomb Bards.

“You,” she said. “Meet me in my chambers after lights out. And take a bath first.”

Rory handed me a bag. I examined it, and it was filled to the brim with dynamite and several types of small bombs and grenades. Remembering how dangerous this stuff was, I quickly added it to my inventory. I’d examine the items from there.

Rory turned to Donut. “Okay, we had a deal. Where’d you find the stuff?”

“The drugs?” Donut asked. “It’s just one neighborhood over, on the other side of the road. We got it from one of those llamas.”

“I knew it!” she said. She turned toward another Bomb Bard. “Gear up. They’ve been holding out on us. We’re rolling on them in five.”

I stood, bewildered as all around me, the goblins—from the level two standard goblins to the engineers to the bomb bards—burst into a screeching frenzy of activity. The murder dozers growled like dinosaurs as goblins piled on. Four copper choppers similar to my own roared to life. The bomb bards all donned metal helmets with a German-style spike at the tip. The tips glistened, shooting sparks. The goblins could light their dynamite sticks and bombs just by raising them over their own heads.

One by one, the choppers and dozer transports rumbled away, filled with screaming goblins. A minute later, and we were alone in the room.

“Did that just happen?” I asked, spinning to see if we truly were alone. We were. “Did we really just start a meth war between the goblins and the llamas?”

Yes, that's basically the quality of writing the entire book. Maybe it gets better later on, a lot of RoyalRoad litrpg stuff that runs long enough either does invariably get better in terms of writing or it just spins out in the mud. Real toss-up on this one given it's sold like millions of books at this point and is only 6 years old but
