Yep, point stands true, more when you realize that the Rock Band crew are the same that left the GH brand to rot after 2 and went on doing a highly successful franchise.

Heck, they didn't have anything to do with Rock the 80's.
I think that what I liked from GH5 was that they left the whole "OHHH SO FUCKING METAL AND I'M A 12 YO KID" to favour a more "all music is good" approach, and that's why I find that game enjoyable, not a masterpiece, but something I don't mind playing.
But then, they got into the WOOHOO WARRIORS OF FUCKING METAL WITH SONGS FOR TOUGH MEN WITH ATREYU AND DETHLOCK, WITH FUCKING MANLY METAL REM AND WHITE STRIPES thing and...well, I gave it a chance, that was my mistake.

At least they improved the vocals a little, but everything after RB3 feels like disgusting crap. :3
