1. 90's
2. 80's
3. 2011
4. the 2000's - 2000-2010
i gamed more in the 90's than ever before for some reason. the 80's i came late, like '88 and 89' with atari and genesis, but i still gamed in that decade. the 2000's were ok but the 2011-2020 is going to shape up the be my best decade yet i just know it. you got the ps4 and the next xbox coming out. maybe some advanced 3d/holographic solutions. hell just this year were going games that are just so hotly anticipated. pc gaming'll go through the roof.
2011-2020 will be my best decade after it's said and done, and the decade is gone followed by it being trumped by the '20's and so on and so forth..
I just hope that the 10s can be as good as the 00s were and that the likes of Hideo Kojima, Tetsuya Takahashi, Masato Kato, Hironobu Sakaguchi, Yasumi Matsuno, Suda51, Takumi Nakazawa, and Kotaro Uchikoshi all develop a good few games each (with a good many Yasunori Mitsuda and Nobuo Uematsu soundtracks to boot).
