I am currently using UE4. I would be stupid not to since I cannot buy Unity Pro (2500 + 1500 per mobile platform (Android/iOS)) 19.00 a month is an STEAL for a triple A game engine. Not to mention the revenue model. I feel Unity is going the wrong direction with their pricing model. Especially with what I am da bawss said about the Eurozone crisis. Although They have been generous in the past for free users shadows, etc. I just think Unity is going the wrong direction with their pricing model. I feel that unity is aiming a little to high in terms of price for those newcomers and hobbyists who use unity. That newcomers will go over to Unreal 4. In the end I think Unity is going to loose out a major share of the market (PC and Console games). Anyway those are my thoughts.
