About time too! I have had a US copy of this game since March and I hope I can now download all those extra songs that the Septics have got!
The game itself is absolutely brilliant allowing 1 to 4 people to play either in the same room or over the net AND you can all play at different skill levels so a beginner singer or guitarist can rock out with an expert drummer! You can also customise you character more so than Guitar Hero. Oh and there are freestyle sections in some songs so you can show off your skillz by doing your own riffs, drum patterns and vocal pyrotechnics for extra points.
The kit is good with a wireless guitar (you will have to buy another one to have Bass too) that I find better than the GH one plus drums which are fun and wired microphone for the vocals.
Its a really social game so just add your mates, a few sherberts and some pizza for a fun evening!
I think its one of the best games. Ever.
