I see. Yeah, exposure for both engines is inadequate atm really. There are few projects that use the 3DGS PE successful: one is the crane demo, another is the fx ball demo, and I think there is a game based off the fx demo. I think all of these are in teh download section.

You're doing the right thing then sniffing around as you are. Another way to look at this debate is from teh angle of development and deployment time. Both the 3DGS and Newton engine have been out for less than a year. Havok has been out for ages (at least 3 years??) and thus it's not unreasonable to pay more for the guarantee of a stable usable product.

GL bro. Keep us posted on your decisions. Even if you go for Havok, your reasoning and decision making that would be really useful posted on the forums.
