An example is when we can't skip a cutscene after watching it once. There must be some technical issue in some games but it comes across as really indulgent. Plus, dude, I just want to fight this boss again.
One I came across couple weeks ago when I played Bionic Commando Rearmed for the 1st time, which drove me nuts, was the inconsistent checkpointing. I would get to a point and die and it would start me at seemingly random locations. I don't mind if the game is tough about checkpoints but not knowing where I was going to start got me pissed.
A follow up question is, what complaints you here from people annoy you the most?
For me, it's the constant nitpicking of technical stuff like performance and resolution. There are for sure games on certain platforms that need to be flagged but the number of games that've ruined my enjoyment vs. the amount of focus it gets...idk. Maybe it's just the internet culture we live in. It almost seems like people enjoy tearing shit down more than playing them. Or maybe everyone feels like their a critic. I guess I could be like this too sometimes but these days, I try to see what a game does right more than what it does wrong.
