This, to me, is a joke for PC/Mac users. $20 for this? I can play BG1/2 on my computer just fine, thanks, with my original copy of the game. That I already paid for. I don't need an extra questline which, in all likelihood, is designed for "casuals."
I could see an iPad user wanting it but otherwise dropping $20 on this is just feeding the money-grubbing, remake-obsessed monster known as the mainstream video game industry.
Why not put your energy into making a new game, not copying what a modding community has already achieved?
