M.A.M.E is your friend!!! I have the XBOX (the old one, not the 360!) filled with all the classics, so I can play them once in a while. You don't need so much time or dedication to play a couple of (emulated) quaters on these games: Xain'd Sleena, TMNT, Slap Fight, Ghost 'N Goblins, Rally-X, Star Force, City Connection, and a very long etc.
Even my wife plays Pacman once in a while!
And playing TMNT/Sunset Riders/The Avengers with 3 more friends that share the memories of old days at the Arcade, in a 50" TV, is a priceless experience :)

Now, I'm getting a Pinball (a real one) to put on my home. I think The Who - The Pinball Wizard from Data East will be a nice one to have. And, by the way, I'm 32 years old, running three business... so I have little time for my passion of Arcades, but still got the mojo!!
