I wouldn't make a special trip for it, but if you find yourself near Colorado Mills mall in Golden there's a couple places with games there. Putting Edge has some newer arcade games and a pair of nicely maintained air hockey tables. There's also two "Tech World" store fronts (one across from Chili's by Putting Edge, another near the Lego Store). The games at Tech World are kinda beat up and dirty, but one store has a Centipede and DK Jr that I'll play (and also a Pac/Galaga with the world's largest monitor crammed into the cabinet that I think makes the game extremely hard to play). The other Tech World location has a Galaga, Ms Pac Man, Tron (but with a non-Tron joystick), Zaxxon, and several 90's games. Since it is on the way home from work I like stopping and playing a few games of Galaga and Tron.
Also, at Southwest Plaza near Bowles and Wadsworth (about 10 miles from where you are) there is another arcade there, but I actually haven't been in it to see what games are there. My wife just texted a picture of the storefront to make me jealous...
