Red faction: Guerilla

I am really looking forward to getting this game, didn't like the demo, though i have been told the game is far better than the demo itself. I watched the trailer a few days ago and it looks fantastic Great physics, great engine, great multiplayer. Really looking forward to getting it, if you haven't seen the trailer here's the link- http://www.youtube.com/watch?v=EE5ecIpTEb4

If you have got the game add some comments and tell me if it is worth getting, cheers. :)
