I don't have one yet, but when I do build my cab, I will have some console games in it. Pretty much anything from the 8 and 16 bit era would be fun on an arcade cab I think (I love the PlayChoice 10 and Nintendo Super System for example). But for N64 and beyond, I would be very selective. Only fighters like KI Gold and MK Trilogy, and digital friendly games like Kirby and Mischeif Makers. Or harder to emulate games like PS1/2/3's Tekken series. If I can get a cheap (broken?) Wii U, I'd love to have Tekken Tag 2 Wii U Edition in there, without the gamepad of course. When I finally get enough space for a driving cab, I would have N64 driving games in it.
So, Howard, I do agree with you to a degree. Most modern games would suck in an arcade cab. But some of them would really benefit. A lot of Live Arcade titles, for example. It just depends on what you are going for.
