Ok it's not a surprise for me !
Why do they want to register people just to try it ?
Caus it's bad actually, you can't make it run at decent speed for all people having standard 3D cards ?
So why advertising it , thay should optimise it, bring documentation, fix serious bugs before selling it !
Smells like Gamecore, some closed thing and closed forums and closed demos, you pay, and that's it
So we can forget this engine for now
