In the 1990s - I was more into Adventure/Platformer games, mainly from Nintendo only developed ones (Mario, Kirby, DK)
In the 2000s, got into more RPGs like Final Fantasy, Mana, Star Ocean, Tales, Disgaea, etc
In the 2010s, got into more western games like Assassin's Creed, Saints Row, Mass Effect, Borderlands, Bioshock, Batman Arkham Asylum, etc
Nowadays I'm pretty much everywhere platform and genre wise (except for Sports and MOBAs/MMOs).
