Here in Orlando there's a place named the "Pac-Man Cafe" which is run by Namco. I dropped by recently. It's got a restaurant that serves things like "Blinky Burgers" and "Power Pellets", an arcade with a decent selection of games (dine there and it's $20 for two hours of play), and a small "museum" area with things like Atari Pac-Man, the small Coleco Pac-Man, the Pac-Man board game, and three arcade machines: Pac-Man, Ms. Pac-Man, and Super Pac-Man.
I collared an employee and asked, "Where's Pac-Man Plus? Where's Pac-Mania? Where's Pac-Land? Where's Jr. Pac-Man? Where's Baby Pac-Man? Where's Professor Pac-Man?" He told me he hadn't ever heard of any of those, then he smiled and backed away slowly.
