Wow! It's hard to guess at how many games I have! Let me see...I have a GameCube with 12 games (My favorite being Metal Arms), a couple Original Nintendos with 24 games, a PS2 with 5 games (I just got the system), a Sega and no games for it because somebody stole them, 15 PC games (my favorite is Shogo), and a Nintendo DS with 12 games (My favorite being Mario Cart). Thats all I think.
