Pac-Man CE is definitely an admirable effort, but there are enough caveats to make it lose a bit of its luster. The controls are responsive to a degree, but get questionable when things get too fast. The graphics are clean, but on the small side.
Namco's microtransaction strategy with Pac-Man: Championship Edition is offensive. You have a dead-end link -- Challenge mazes -- right off the main menu. To ask the player for money mere seconds after charging for the initial download is a slap in the face.
