Patch is out now!
Just quickly messed about with it before bed. They've made some interesting changes to the riff repeater:
Good
Pressing start while playing now reveals an extra menu option that lets you change the mastery level. You can use this to boost a level up to 100% (and interestingly you can also de-level a section, even back to the start level). It seems if you beat it you go straight to that level, so I assume now you could jump to 100% instantly if you were good enough?
Bad
You no longer have 5 lives in riff repeater!
...But instead you now have 30. There seems to be no way to change this that I noticed, either. Might sound a lot to the uninitiated, but trying to learn the most difficult solos in this game (i.e. Free Bird) will probably take the average player easily ten times as many lives to achieve. Why was this not made infinite for God's sake?
Haven't tested the the event crashes yet, but despite how shoddily this game has been handled I still can't imagine them having the gall to release a patch without that fixed.
Also, apparently next Tuesday will see the next DLC release, which will consist in some way of Pearl Jam track(s).
