I have to agree with Ortucis. I put this engine thru a lot over the weekend including trying to get their tuorial working. I had many hang-ups, glitches and it just wouldn't work without restarting. It was very annoying. Also, as has been mentioned. You are going to need the pro version if you really want to do anything with this seriously. btw: I used a brand new dual core system with 9800GT card to test with. Just not all that impressed.
