If you’ve any interest in videogames, you should at least play the demo. While it’s going to be disappointing to some people – and I’ll explain why in a bit – this is absolutely one of the cutting edges of videogames at the moment. That it does what it does so naturally almost undersells its achievement: it just works. The difference between the demo and the full version is that you simply get a lot more parts out of which to construct your creature. Which, when written down, makes you wonder why anyone would pay for it. It’ll all be in the game eventually, and you can have a crack at a fair chunk of it now… why pay?
