I gotta agree with this (in fact, I pretty much agreed before this video was even made.) No matter how simplified or educating a game can be, there’s still going to be the people that dominate everyone else in a game.
I actually had that experience with PlayStation All-Stars. I practiced playing as Big Daddy in training mode and against the computer a lot. I think playing against the computer is honestly a good way to develop execution, but there is a ceiling when your execution is good enough. The real joy didn’t come until I regularly played online. I kept losing a lot, not quite knowing what I was doing wrong. But the funny thing is I actually was recording all of the matches, and I went back to watch them and saw all of the mistakes I kept making. So I kept playing until I eventually started doing stuff like utilizing space properly, studying moves to see what’s punishable and what’s safe, getting around attacks that seemed impossible to avoid. I developed the fundamentals from losing to human players better than me. It felt so much better winning when I knew what I was doing.
But it’s been a while since I played it. I would definitely like to put this practice into other Fighting games when I get the time to do it.
