And on a side opinion note, when they announced the reboot for both GH and RB, I was 100% RB, with a system I knew and re-download your DLC... but the more I think about it, I usually solo guitar games (not huge into the social playing) and my FAVORITE thing about guitar games is the skill progression you got first learning how to play - that's gone with Rock Band 4.. You already have maxed out your skill... While with GH Live, you get the fun of raising your skill again with a revamped key layout. AND I love the free streaming-like service in GHL. You always get new songs for free... and it'll introduce you to good new songs (and a bunch of bad I'm sure)
All that being said, FMV is dumb. Really dumb.
