Mainly rpgs here, especially Jrpgs. I've noticed some of my tastes have shifted over time. Now I really enjoy a good shmup but I've really fallen off of the FPS genre, partly due to the limited field of view. I can't stand that. And my love of 3rd person games has escalated greatly. Also I've noticed I suffer occasional nausea for some FPS titles. I've also stopped playing most MP titles save for couch co-op stuff with my gf. Partially due to free time and scheduling differences with friends online, plus I don't like playing with strangers very much. Also the sense of accomplishment and satisfaction in completing games in my backlog is far great than just hanging out with my old game groups back in the day. Fun though they were, its just such a time and often money sink since the industry went so strong into GaaS. I'd say since the 360/PS3 gen my backlog grew exponentially because I'm the kind of guy that's got to have and see it all, but MP really does demand a lot of commitment.
I've also grown very tired of the Action Adventure type, namely from the west. They are the same game from the PS360 gen with slightly better gfx and now weaker stories and characters. The same gameplay design is holding them back, with the forced walkie-talkie sections masking load times and offering "character development". Its up there with the ol' audio recordings doing the same thing for cheap. Except now I've grown to prefer the later since I can still run around and play. I much prefer it if devs make a game with story to have actual cutscenes with direction.
