I really like both physics games and turn-based strategy games, which arguably are related in that they both require a high degree of internal consistency and simulation modeling in order to be very good. this is obviously a requirement of games that have good symmetrical multiplayer but I tend to lean into it more in single-player stuff.
I wouldn’t call it a particular interest on its own, but I’m extremely picky about UI aesthetics and even menu sound design (much moreso than the actual interface UX); it’ll keep me playing a game I might’ve put down sooner, make me give up on one I otherwise sort of like, and nudge already great games to classic status for me.
I have a major weakness for Macross-style music climaxes and I can’t understand why more people don’t use them liberally in their pulp storytelling.
Oh, and I like it when games actively antagonize you as much as possible, as long as they respect your time.
