A recent online discovery seems to indicate that Bandai Namco is working on a new Pac-Man game, as the company has registered a new trademark for "Pac-Man Maker". We don't have any details on what it might be, but it's easy to speculate it could be a game similar to Super Mario Maker, albeit dedicated to the old Pac-Man formula.
In other words, it could be a game that would allow gamers to create, edit, and share their own Pac-Man levels. Once again, this is all speculation, as there's yet no official statement or announcement from Bandai Namco, so take it all with a pinch of salt, but it's interesting nonetheless. Would a Super Mario Maker-style game for Pac-Man work?
