I've just started playing Tribes 2 again via Tribes Next, so I'm in just the right mood to get excited about this teaser trailer for Tribes: Ascend. It has everything you could want: jetpacks, classic weapons like the spinfusor, and it only sort of looks exactly like Halo Reach.
I do have one qualm, however: Tribes' visual style has always been very colourful, but the new game is built on Unreal Engine 3, which means that everything looks dull and hazey because of way too much HDR lighting. It's possible that the developers at Epic all have cataracts and can't see properly, but when I go outside (it happens) I often notice that the real world looks nothing like Gears of War or Bulletstorm. You can argue that the style of those games isn't meant to be realistic, but it would help your case if the style were actually good.
