I simply dont like so much this kind of marketing strategy

I would prefer something like " Unity3d cost 1500 usd being much better than the competitor "
Probably it is true , unity3d really worth the money

Otherwise the price scheme must be consistent with the actual use of the sofware

Game Core 2.0 did it

Pro version is really for Pro users, only

I dont know whether Game Core 2.0 is good or not but I can not but appreciate this decision
