Grafix look good. seams for me it runs smooth. Glad to see that the 343 Devs fixed the Fixed and Phased settings in Valhalla. 
I would like to make a suggestion or two:
- It would be nice to have a Next Button in Pre-game so you could pick the starting map you want.
- Was wondering if it would be possible to mix games/maps in the custom game browser in the future?
Example: Run a map from Reach and be able to run another map from Halo 3 in the custom game browser at the same time.
Thanks ')
