I'll give it a shot. I love sci-fi, and I love mechs and the like. Looks like it's a LITTLE bit like GoW, but moreso looks like its own game. I do not think the demo would be a good judgment of this game personally. A good example of this would be any Capcom gae, decent demo that you can't do much with, but then you get the game and it's WAY better than any demo.
So, I reserve my judgement til I play it, but it looks like my cup o tea.
