OK ... I'm trying to see enough added value in A8 to justify the upgrade cost (and going from A7 PRO to A8 PRO won't be all that cheap, I'm sure).

Some others have already mentioned their disappointment with respect to the list of enhancements / improvements, and while I can appreciate a new core for multiplayer support, shadows and some other improvements, I can't say that it makes me yell "WOW".

Every engine has its strong and weak points and A5/A6/A7 have helped me understand more about 3D-engines then any of the other engines I've used/owned (Torque3D / Lawmaker / BeyondVirtual). But since this is still just a hobby, the truth is that there are very capable engines available free of charge (e.g. UDK)- or for less money than the upgrade will most likely cost - that produce superior results in many respects.

I'll wait and see what the "final announcement" for A8 containts, but now maybe is the time to sell my A7Pro and move on ...

Cheers,
Andreas
