Avowed was very mid. I enjoyed it enough, but nothing about it was particularly brilliant or terrible.

Mighty no 9.

The Technomancer

The incredible adventures of Van Helsing. Decent rpg with loot but was fairly imbalanced among character classes. The real winner was the mini tower defense games in it and the spinoff tower defense game, imo.

Pretty much every korean MMORPG released from 2006-2014, as they were desperately trying to be "World of Warcraft, but better". Perfect World, Aion, ArcheAge, 4story, Granado Espada, etc etc etc, even when you have the better experience of playing on a private server with significantly less P2W (as in, nearly everyone gets most of the shop for free)

To me, personally, ArcheAge would be the best fit for "dead medium quality". It boasts naval combat, which is meh; player run trade caravans, which probably only worked as intended in the first 2 months after launch; limits on gathering and crafting, which just forces free players to buy premium; graphics are the generic korean mmo variety, pretty but almost impossible to distinguish between games; music, enemies, dungeons and most gear exist

we are in a golden age of medium good action games. lies of p, stellar blade, khazan the first berserker, another crab's treasure come to mind for me.

non-fromsoft soulslikes are starting to find their voice. they're not quite great yet, but they're competent now.

I suppose Resident Evil 8? The scares weren't very scary, the exploration was all very fake, and the bosses all showed up for attendance. It definitely functioned, but it didn't impress in the way previous entries did. It wasn't frustratingly bad like 5, nor was it interestingly bad like 6. It just felt like a lesser version of what they've given me before, somewhere between 4 and 7.

Greedfall

Generation Zero. Primo aesthetic, sometimes well balanced, good with friends but not so much solo.

Well, when it comes to video games, despite being foundational, Mario Bros. At the time, it was mids, but there were a lot less truly great games, and less abysmal ones so it looked better than it was. The series got better, but that first one was kinda meh. It's all timing jumps, which is fine as far it as it goes, but there were both better and worse options on that console.

Away from video game, Life is about as meh as it gets. No real strategy, no depth. But it's a good time killer and you can play it with a table full of people drinking and not get bogged down or into arguments because of the game (unlike monopoly lol).

Rogue Trooper

Sackboy a Big Adventure. Absolutely no ill will towards it, and the issue may lie more with me than the game, but it just felt very "okay" for me.

Assault Spy comes to mind.

And Mad Max maybe?

Minesweeper

I remember feeling this way about Die Hard: Vendetta for GC. Strong meh/10.

Atlas Fallen. Having played it, all I can say is that it doesn't elicit any heightened emotions from me.
