To be perfectly honest, I've yet to hit any problems with my project. I'm also spending a lot of time writing VB code for the main part of the engine. I have quite a way to go before I get heavily into the 3d Parts. I'm not sure how far other people have got with stuff, but what ever problems I may encounter, I've 101 other things more to get on with, and actually finding ways round issues that have cropped up in the past (With DBPro) I found better ways of doing stuff anyway without hitting problems.
