I'm not underwhelmed. I see the potential. They've launched few games, its true, but there have implemented a lot of great features like the ability to rewind, friend challenges, 3D accurate cabinet models, high score tracking, automatic demo recording of high scores and uploading to XBL for later viewing, and a lot of other great stuff I haven't messed with yet. The ambiance is fun and the arcade sounds great. All that's left is to add more game packages to the arcade, which will happen over time as Microsoft makes deals with the copyright holders. The framework is there and easily extensible to include tons of new games and emulators, I think its great and an impressive start.
