Forums can help games a lot and while mobile games generally tend to have support for social media instead of extending towards forums and whatnot, I think it'll only help. I personally chanced upon the forum while googling for Ramsay Dash tips but I think this place is decent and will get better with more people sharing and discussing about the game here.
I know that there are several YouTube channels and Facebook fan pages/clubs but there are people like me who prefer forums or don't have Facebook, et cetera. It's still community building.
There could be some kind of incentive in the form of supplies/coins or something like that for spending time in forum.
Thank you for reading.
