So, I downloaded the demos to both of the geames, and here are my impressions:

Omega Five: Really quite fun. I love shmups, and its nice to finally see a new one, and not a port of an arcade game that is basically unplayable at this point in time. Will def pick it up at some point.

Tron: How this got past QA at any company is beyond me! The game is an absolute atrocity, and is so unplayable it needs to be seen by all. The sound is hideous, the graphics are nauseous, and along with Yie Ar Kung Fu, this ranks as one of the worst XBLA games by far.
