All these maps are still free, though, right? It’s nice they are trying to reward the content creators but just wondering.

I am not disagreeing with you but many times tech demos are being run on total beasts (think $4-6K worth of computing power). So they may not want to dissapoint by releasing. However, it would be nice to tone down the demo to run on the system since I am sure games will come out with those engines soon enough and run fine on a $800 system.
