An award-winning title for a good reason, Pac-Man™ Championship Edition DX+
is definitely the best Pac-Man game that has ever been produced, it's incredibly fun and never gets boring, even if you aren't really a Pac-Man fan, it's just simply that good.
This game offers you the chance to play classic (or not) Pac-Man however you feel like playing it, tons of variation, options, alternate-graphics and play-styles to choose from gives this game a really long lifespan and tons of replayability. There are game modes and challanges for almost every factor that exists in Pac-Man too, I'm pretty sure if you can think of a challenge, there is an option or game mode for it available somewhere in this game. There are also global and local leaderboards, ranking systems and many variations of maze-layouts to choose from too!
Whether you are a fan of the game series or not, I couldn't recommend this game to you enough, particularly when it goes cheap in the sales, pick up the All You Can Eat Edition
if you want to add even more variety. This game is definitely more than worth the money, I would also recommend buying this over Pac-Man Museum
(if you want a more modern Pac-Man that is) as the Pac-Man Championship Edition featured in that collection is vastly inferior to this version.
