Been going eleven years strong now. Since GH2 days. There have been times I've taken an extended break, but I always come back. When I get tired of Rivals I play customs, and vice versa. Only thing that could stop me would be losing finger dexterity. Definitely a bit stiffer now compared to 2008.
Me too....my fingers get stiff before playing a song. I'm trying to losin' my fingers and arm to be comferable on the neck. GH/RB community will stay strong as long people discover customs. When Clone Hero was made people from GH games from past are jumping back in because of that game.
