I don't have a 360 but I love beat em ups and occasionally play them online with MAME or other arcade emulators.
The main one I play is Street Fighter Alpha 3, but I also have a blast at King of Fighters, Guilty Gear, SFII, Marvel Vs Capcom 2 and Smash Bros.
A night of beat em ups would be an excellent idea. I loathe the fact that I was born in the generation after the booming arcade scene because I was too young to go to them
