OK, UT3 is like $10 on steam. If you have ever played one of the UT games you will know how mindlessly amazing they are. then if you download the Ren-x beta you can get a strategic game that is more amazing, in the end you will have 2 games for $10.
From what I hear most people are waiting until it is a standalone but if you get it now you can have an edge on all the other people who are still admiring the scenery when you have experience in-game. :lol:
ID what you should do, it is up to you
