Now that that's out of the way and I've shocked and amazed you with my run-on-sentence skills:
Why are the graphics capped on the Xbox 360 version? It seems like the 360 version is running in 420p. The Xbox supports 1080p and even native monitor support if you're using one. Don't get me wrong I love my gaming rig but I'm not one of those guys that blindly thinks that my PS3 and 360 can't run the game in a higher resolution and frames per second. Are the frames per second locked on the Xbox as well? Will the 360 version get some support for higher resolutions and frames per second?
The server browser would have worked on the 360 version and the game play would be spot on with a handful of dedicated servers. Gears of War 2 svcks balls through a sweaty straw compared to the Gears 3 beta. What makes the difference? The Sawed-off Shotgun. I'm kidding. The dedicated servers make all the difference.
I also noticed that some of the maps don't seem to have quite the same dimensions. Some jumps seem closer on the PC and surprisingly the mouse and keyboard is really effective for the parkour stuff. Before you PC-purists spoke applesauce in your pants, the controller is infinitely better for parkour and shooting at the same time. The only reason the mouse and keyboard has an edge with pure parkour is that you can turn from side to side much faster and therefore facilitates fluid wall jumps and transitions to extreme direction change.
All and all, the PC version seems so much more polished than the Xbox version which is disappointing to me. A few changes would definitely go a long way towards keeping the 360 version alive.
The main change that I think would give the Xbox version a much needed shot in the arm is a server browser or a matchmaking system. One the reasons why Call of Duty and Halo are so popular with the majority of console gamers is because it's easy to just get together with friends in a party and move from match to match. When you take these guys out of their comfort zone they get antsy because games like the Call of Duty series have pampered and held their hands so much that they don't seem to recall what games were like before you pulled the left trigger and the game snapped onto the nearest target for you. Add that to the fact that many of the purely console-centric players are all ready out of their comfort zones in a team objective game that doesn't have team death match and it's not hard to see why the Xbox gamers don't seem to be playing the same game that those of us who like it are.
Anyway, that's my two cents, for what it's worth. I like the game, it didn't get a fair shake, and I hope that future support will smooth out the rough edges and not only keep what community we have playing but also bring back a few of those who may have judged the game too harshly and/or prematurely.
