Oh they are the same thing , the differences are so minute and pointless they dont count. Atari to Nintendo ? A6 to A7 is nowhere near that , it's the same garbage. Well A6 is not garbage, i'm quite happy with A6 , but A7 is garbage as an engine upgrade if you already have A6 , if on the other hand , you dont have gamestudio , then it's still a decent engine , but still , no where near where it should be , I mean , this people are suppossed to have a staff working on the engine full time , and this is all they could achieve in the yrs A7 was in development ? C'mon , Matt achieved more with Sphere and in less time , Sphere plugin would be a better upgrade as an engine than A7 , what a pile of turds.
