@Sinha - Ikaraga and Puzzle quest are both good XBLA games with 28/33 reviews respectively.

Geometry Wars has 27 reviews, so its not that likely to fall under 90 at this point.

You never know.  It has an average of 90.2% right now.  One 4 of 5 review would make it 89.9%

 

 Except that its a "weighted" average and we don't know what different values they ascribe to different sites. I did some math before I found that out and it has more "scores" above the 90 mark than below, just from sheer numbers.
