Last Tuesday we got a new PS3 game. On Saturday we got our bass guitar fixed. These two facts are related.
The new Rock Band game came out on my birthday! :) It's a return to more of the pre-Guitar Hero gameplay from Amplitude which was a game Harmonix released about 10 years ago - I remember we were playing it on the New Year's holiday we took with Rachel, Ellen, Gordon & Ainsley and that was New Year '03 iirc. So there are no fancy controllers needed, you play it with the standard PS3 (or Xbox) controller, and it's a single player game as far as the actual playing experience goes.
