Here's a thread to provide some escape from all of the 2.1 nattering. I downloaded RoboDefense Free, played through it, and really like it. Then I downloaded Tower Raider Free and I really like that one also. I'm ready to go ahead and get one, but the reality is I don't have enough time for both. Which one would you get? I like the notion of the teleport in RoboDefense (although I haven't played it yet), but the variety of the maps in TowerRaider really looks cool. How's the performance of Tower Raiders at the higher levels when the screen gets full of towers?
