I have Medal of Honor Allied Assault: Breakthrough and Command & Conquer Generals: Zero Hour PC expansions for trade. Both are new and sealed. I am not a PC gamer, so I don't have the originals to run these. Specifically, I am interested in GameCube, Game Boy Advance, Xbox, PS, PS2, and Dreamcast games, but I also collect for NES, SNES, and Genesis. Let me know what you have, and we can work out a deal.
