Here is a rough, but fairly accurate account of mine...
Wii: 8(TP, Wii Sports, Wii Play, SPM, Godfather, Red Steel, Rayman, Splinter Cell)
VC: 5(R-Type, Toejam and Earl, SimCity, Wario's Wood's, Ice Climber
DS: 25
GBA: 35-40
PS2: 30-ish, give or take a few
X Box: 25-ish, give or take a few
DC: 8 or so
N64: 25 or so
SNES: 20-25
NES: 25-ish
GB/GBC: 10-ish
Genesis: 8, maybe one or two more
I'm buying many more games for the classic consoles(GB/NES-N64/DC) these days than the newer ones.
