In order to pay the bills, you have to sell everything. You can afford to keep 10 games. What would you keep? (Due to lack of funds, online gaming is not an option.)
My picks would be:
Final Fantasy 10
Skies of Arcadiia
Space Channel 5
Virtua Fighter 4
Banjo-Kazooie
Ratchet & Clank
Soul Edge/Blade
Dance Dance Konamix
Goldeneye
Nascar Heat - Dirt to Daytona
