-I like that the video's seem to be loading a lot faster than Halo 3.
-Allowing everyone to put tags on peoples file shares ends up with offensive tags.
-I've noticed at certain times when I press the Y button it will not release the camera for free roam.
-Debris and sparks left behind from explosions.
-One thing that happened in Halo 3 that I would like to see gone from Reach is that when you press y to return to attached camera view if the player you are watching is dead it goes to another player. Would like to see it go back to the player you were currently watching.
