Me and my cousin spent waaaay too much money on this arcade back in the day. We never finished it because we were stupid and kept going back for more tokens and starting the game all over again. Worth every penny.
One time, my friend set up 2 separate linked PS2s with 2 separate CRTs and 2 separate GunCons just so we could get the full arcade co-op experience. It was completely worth it. Bless this game.
