I usually like games that have high Metacritic ratings, so I tend to buy and play popular games.

As for unusual facts, I guess I like types of games that get more enjoyable the more you play them. So I like 3D Modern Sonic games (except Forces), because I like the level memorization (as well as the reaction stuff). And I'm really digging Persona 4 Dancing All Night because the songs get more enjoyable the better you become (I've never played a rhythm game before).

I also just like games that have a good aesthetic. Games like these could be: Freedom Wars, Atlus stuff, Pokemon XD Gale Of Darkness, Sonic Unleashed (it's like a pixar movie), Gravity Rush (it's like, french), some Castlevania and Metroid stuff.
