I think that my biggest problem with games is mostly player and developer related. I do not mind people trying new things, but if you don't like a genre, don't make that genre. You upset the people who love that genre and the genre you are trying to turn it into, won't like it, either. I can forgive systems, as long as they work properly and doesn't remove player interaction with the game. If it doesn't work, is a pain in the rear, doesn't make it fun or removes choices from the game, then, it is a peeve of mine. Games that have systems that don't work, Live a live, Final Fantasy 13, Final Fantasy 12...Now, if it has interesting characters and a good story, you can overlook any bad system. For example, I hated the gambits, but otherwise, the characters, and story of Final Fantasy 12 was really interesting. Final Fantasy XIII had none of that and I honestly, fell asleep or fighting falling asleep.
Player pet peeves are the people, who have shallow dislikes and won't play a game with certain systems, even when it has interesting characters, story. They are overly critical of some games that their dislike list is so long, you wonder why they are using rpg maker and not other game engines. (Lucky, I am not talking about anyone on this forum, or at least, none that I noticed.) But I was talking about Kitase, and his dislike of RPGs, trying to turn Final Fantasy into a FPS, when he should just work on those types of game. I am all for growth, since Final Fantasy has been in a rut since Final Fantasy VII, but they are not fixing the problem when they do not even know what the problem is. Too focused on the world when everyone loved the old Final Fantasy just fine.
