Usually gameplay mechanics that I like. For example I suck at puzzles and feel like they awkwardly break up a game a lot of the time so I avoid Resident Evil style games that feature them. Same thing for any game that uses a card based gameplay system. I get them a lot in Humble Bundles.

I stray away from fantasy games because I feel like learning the background can sometimes be a challenge.

For me it’s mostly first person single player games with decent soundtracks. If it’s got a bit of grittiness and companions you grow close to I like that.

Speaking of which if any of these games sound like they were recently (past 6ish months) in Humble Bundles comment the game below and I’ll probably be willing to give you the code.
