...fun, fast, and the graphics are absolutely gorgeous. The maps are insanely well laid out, the characters move with a natural, smooth, and slightly cartoon, action movie, style. My only real complaint is that it seems to me that the weapons are all heavy damage, slow firing weapons. They don't seem to have any speed to them. When you aim at someone, it takes awhile for the weapons to warm up and then fire, and then there is a lag time for them to warm up again. What this means is that your accuracy is off if you're not used to the weapons and their fire times. It also makes the sniper weapons harder to use in my opinion.
I was all set to buy this when it came out, since I have spent countless hours playing UT. I downloaded the demo and decided I didn't need it right away. It certainly looks a lot better than the original, going for a more Q3 shiny look. The people and weapons are bulkier and harder to control. I am looking to buy this after it hits the $25-30 price point. Good to see someone else had that opinion on the weapons.
I have found it helpful to do the stretching exercises my physical therapist recommends. Do some core strengthening exercises, such as the ones highlighted at The Mayo Clinic. By keeping your core strong, your back won't put itself in a position to cause that sciatica pain you are having.
