And can I suggest having an arcade as well: Neo Geo Big Red. Multicarts works and Samurai Showdown is always sweet! Especially Samurai Showdown V Special and shmups are great too.
Arcade 1up count as well: I just beat the shit out of Shao Khan on a Mortal Kombat Arcade 1up on UMK3 and my beer suddenly taste better! ;o)
Cheers,
Chris
