Namco is honoring its 50th anniversary by releasing this compilation of arcade classics. Using a retro interface, you check out a virtual arcade hall where you can select each classic in its original arcade cabinet.
Exclusive to the Xbox version are Live Leaderboards where you can post high-scores.
The game's Japanese release, Namco Museum Arcade Hits, has a few differences from the original US/European releases: there's a different soundtrack for the main menu, and both Pac-Mania and Galaga '88 are unlocked right from the start.
After beating certain high score criteria, Pac-Mania and Galaga '88 become unlockable games, finalizing the console/PC roster to sixteen titles.
