N 64, Gameboy advance, PC - Power Rangers (lol)
PS2 - Can't remember the name, but it was a package of games, sort of like the orange box.
Gamecube - Super Smash Bros Melee
Xbox - Halo: CE
Xbox 360 - Halo 3
First PC game as a older kid - Runescape
Nintendo DS - Pokemon
I think that's all. So first game would be Power Rangers. (Might've actually been some Elmo game when I was 4, but unsure of whether Power Rangers was first or not)
