So as mentioned elsewhere, I'm building a MAME cabinet this summer. It's a project that I've been thinking about for several years now, and I think it's finally about time I did it. Right now I'm mostly focused on just getting it together, but sooner or later I'm gonna' have to start thinking about what to put on it, so I thought I'd use the opportunity to get an arcade game recommendation and discussion started.
Also, I'm by myself 99% of the time and don't have many friends who are good at games. Right now I just want to build a one-player cabinet, but are there any really crazy two-player things I might miss out on if I do?
PS: I've been saving that thread title for like a year.
