Even though it's just an early beta, I'm playing FOTRSU as my main install and enjoying it greatly. I was never a fan of TMO, so in the past i usually just used various mods to fix what i disliked about the stock game. .ie better persicopes, a useable radar screen, and many many other things that i had to merge together. In FOTRSU it's all there and i don't have to do anything. I've done very very little in the way of customizing the mod.
It's awesome sauce.
