I was shocked by this offer, but when I tried the whizzle demo, I knew this isn't the engine for me, at least not for my sort of projects.
The whizzle demo has a very simple scene low resolution, unplayable framerate and no option to change that, yet...
Sure, it is my pc, but HL2 runs fine - maybe, valve follows epicgames tommorrow! grin
