First platform was a computer. I've had a NES too, or I think that's what it was. I was very young and didn't know much about anything at the time, I used to call it my TV game, to distinguish it from my computer games. I played very little at it (couldn't get past World 1 in SMB and Duck Hunt got boring after a while) so my parents gave it away or something.
So I've always been a PC gamer, my first real console is the Wii my girlfriend and I got this Christmas. Grew up with the games from the 90s, then at the end of that decade my friends and I all formed a LAN network within our apartment block and played Starcraft, Half-Life, Diablo II, Counter-Strike... ah, the memories.
