Microsoft defends Pac-Man CE pricing

During the Gamerscore Blog's
Lunchtime Conversation, Xbox group product manager Aaron Greenberg
defended the pricing for
Pac-Man Championship Edition. Greenberg went on to say that
Pac-Man CE is not a simple port of the old game, but is almost a sequel in it's own right with new gameplay, artwork, music and HD implementation added. So, he feels that the 800 Microsoft points that the game costs is more than reasonable for what you're getting.
And if you're a regular
Fancast listener, you'll know that we were all impressed by the new
Championship Edition and most of us were happy to plop down our Microsoft points. We also agree that it's more of a sequel than anything else, but it's ultimately up to you if you think 800 points is worth a new (and extremely fun)
Pac-Man experience. So, is the pricing overkill or is it in line with other Arcade offerings?
