I don't think my tastes have changed much, but I have been more and more exposed to different genres, expanding the realm of types of games U like. I never liked FPS games, but recently I have enjoyed playing games like online co-op in Resistance 2, Borderlands and MAG. I was never into Mega Man back in the day, but in 2005 when I tried MMX for the first time I loved it and have become a huge Mega Man fan.
But I still love all the games I used to.
