Now, at first I thought this thread was supposed to be about which cabinets you wanted. Not which games. Cabinet choices are a little different.
For vertical games nothing beats the Midway Pac/Galaga/Bosconian style cabinets.
For fighting games, sports games, and scrollers I like those 33" cabinets that have the control panel on a separate little pedestal.
For older horizontal games I like Williams cabinets. The monitors being right at eye level helps you to see EVERYTHING.
When in doubt, you can't go wrong with an Atari cabinet. They usually have great artwork.
The Buck Rogers cockpit is especially cool looking, even if the game isn't that great.
Now, as to which cabinets I actually do own?
Assault, Turbo, Jamma cabinet (Former Arabian), Top Gunner (Former Galaxian), Kangaroo, Crystal Castles, Artic Mini, generic gambling upright, Carnival cocktail, generic cocktail, Time Pilot cocktail, and a Jack the Giantkiller cocktail.
