Doesn't tie-in ratio = games that were bought new? Used stuff doesn't count, correct?
Anyways, I own...
Metroid Prime 1/2
Pikmin 1/2
Animal Crossing
Luigi's Mansion
SSBM
Wind Waker
Viewtiful Joe
Paper Mario 2
Super Mario Sunshine
Mario Kart: DD!!
Resident Evil 4
Sonic Collection
Mega Man Collection
Eternal Darkness
Rogue Squadron 2
Donkey Kong Jungle Beat
Killer 7
SSX Tricky
Super Monkey Ball
Mario Party 5
THPS3
That's 24 games (not counting my two Zelda collections and Metroid Prime 2 demo), and I only bought 13 of them brand new.
