I haven't counted in ages, but a rough guess would be 200-250, not including the 60-odd titles I'm trying to sell right now. It's mostly because I buy lots of games dirt cheap (like yardsales, game clearances, and $5 last gen titles) and by the time I beat them (If I beat them) they're worth pennies, usually a dollar or less. Most of the time I'd rather keep it then have an extra .50 cents or whatever. For my systems, I'd guess I have about 15 Snes, 3 Nes, 12 Wii, 30 N64, 3 Virtual Boy, 25 Gameboy/Advance, 10 Ds, 30 Gamecube, 15 Genesis, 15 Saturn, 20 Dreamcast, 20 Ps2, 10 Playstation, 35 Xbox, and 25 Xbox 360 games.
