That's a very good question, right? It definitely had more eyes on it with the rise of Game Grumps and he has said on the show a few times, the band used to be struggling. That's the crappy entertainment industry for you, though.Would anyone care about NSP if not for Grumps? Because that's what I was getting at. If Dan had only been involved in Steam Train and it had petered out, no-one would give two shits about it.
If you can't make 1 mil in a week, you're poor RoI, thus not worth investing in.
Dan is clearly passionate about the band, so it is definitely in his best interest to stay with GG, to get more eyes on his band.
