I have recently played 3 games that have forced a lengthy, unskippable tutorial section that runs for several hours of the game, just to unlock the most basic functions like buying the items, customizing features, multiplayer, and even 2-player split screen modes.
For 2 of these games (Armored Core 6 and Gran Turismo 7), the major draw for me was the MP and I haven't even gotten to check out MP yet because it's locked out until you get passed a certain point in the progression system. Fuckin' why do any developers do this? I just wanted to play with my sister but we have to get through most of the fucking game before we are allowed to do the multiplayer modes. Such bullshit.
I would probably have done it at the start of Chapter 2 rather than the end, but Chapter 2 (on NG) is pretty short anyway. The main idea is that you have faced two (and a half) different boss types by that point and should have a good feel for how to use different legs, have a good set of weapons, etc. Which, since there is no concept of Soul Memory or even progression based matchmaking, is kind of needed to prevent people's first experience with AC6 multiplayer being the starting core getting demolished by double Zimmers.
And it isn't half the game.
spoilerChapter 3 is pretty long and 4 and 5, while somewhat short, are brutal.
What I do disagree with is holding off access to the store until late Chapter 1. But I also get that people will likely be overwhelmed by the store rather than excited, so it is probably a good approach. Let the player know how to swap out parts and what not before letting them run free. Still don't like it though.
