What systems have ya got? And how many games for each? Since we all have our histories as gamers, it does give a decent feel for each other's tastes.
NES - 17
Genesis - 26
SNES - 3
Gameboy - 2
Saturn - 16
Gameboy Color - 3
PSX - 5
N64 - 34
Dreamcast - 18
Gameboy Advance - 6
PS2 - 12
Xbox - 4
Gamecube - 5
PC - I'd guess somewhere in the mid 50s to 60s easily.
We had some Commodore 64s, but the only games I ever remember playing on those were a Batman one and a Star Wars one.
Looking at my list... good lord have I spent entirely too much money on games
