Oh yes, no problem at all, I understand why they would keep some sections of the site for registered users only (and it's actually a great idea to motivate people to buy the engine), the problem is that in my case I want to know and understand the engine very well so that I'm fully aware of what I can do with it and what I can't before I fork 200$ on it. I'm a professional developer and as you can imagine I can't use pirated software. I have a tight budget and I pay for all my studio's expenses myself, and while 200$ isn't much at all (even less than the studio rent) I need to watch for every penny I spend.
But oh well, from what I've seen from the tutorials, videos, and some small experiences I did, the engine is very strait forward and is actually much easier to work with and is a lot more powerful than the engines I've worked with previously (including our own engine) so I'll probably buy the SDK.
Keep up the good work guies !
PS: about wh1sp3r, just because he has the full version now it doesn't mean he didn't have the "evaluation version" before he bought it.
