I meant Pacman Museum, not Namco.
After some more playing, my opinion has changed from "meh" to "different".
Basically, vanilla championship edition is like classic pac man, where you're always on the run from ghosts, while in DX+ they're never really a threat because of slow-mo and bombs. So the challenge isn't survival, but racking up points.
Makes for a much faster paced game, but tbh vanilla C.E. is more of a proper pacman game. C.E. is Forza, and DX+ is Burnout.
Anyways, besides C.E., the Pacman collection has an Arrangement game from the psp which is worth the price of admission alone. Really fun to play.
Of course, I could have just emulated the rest of the older games, but the leaderboards are worth paying into, imo, plus achievements give you some goals and keep the games from getting stale (And there are over 72 of these things. Only like 3 people completed them.)
