I only have one arcade game and its Black Tiger. I really wish I had a ton more room cause I actually find arcade stand ups pretty appealing. But, as it is, with the room I have only one will fit. I would like a Ninja Gaiden stand up (I could have gotten one years back for $50 complete and I still kick myself for not getting it at the time) and a UMK3 machine. There is also a really weird Dragon Quest stand up thats Japanese only (the one the crazy controller is designed after) but my chances of finding one are pretty slim to none.
Ive got a few board games. I have 2 different Pac-man games, the Legend of Zelda game and a SMB game.
