Someone should recreate this island in A7 to see the difference between the two visually. As far as I am concerned, you need Unity Pro for a game which requires basic stuff like shadows for ambience. Like I said, without all this basic stuff the games would have worked on Mac but on Windows you will compete against a lot more high end games with equal or better engines. When you go 3D, you open yourself to AAA market audience, who are graphics whores, whether you like it or not. Hell, Quake 3 engine will make this island demo look like Quake 2 demo..





SO, the tools are good and will let you create a kickass, fun game, esp. if you are an artist. Just be prepared to actually purchase the pro version before releasing anything 3D using Unity.
