There's certainly nothing illegal here, but it feels very... scummy? A show of bad faith? It's certainly not extortion, but raising money for DLC before the game is even out yet seems like a pretty bald-faced example of money-grubbing, especially when we're talking about a project that's made more than $4 million. I understand that budgets can be tough things, but when you make more than 4 times your original goal (or, for another perspective,
10 times more than Half Genie Hero's starting goal, which offered all platforms from the get-go), I find it hard to offer anything more than the world's tiniest violin.
Personally, I just haven't been very impressed by what I've seen of the game so far. The Beta is really easy, even on the hardest setting, and forcing players to use the dash for enemies is a gimmick that wears off fast. Plus, it just looks... I don't know, kinda ugly, aesthetics-wise. Add in Dina's antics (most recently, banning backers who tweeted on GamerGate) and the fact that the company has refused to acknowledge them in any way, and all the initial luster around the game and Comcept itself has kind of worn off for me.
I get that people want another MegaMan, but honestly, it seems that Inafune is just taking advantage of people's nostalgia here. Like Kamiya said, he's a business man, and a good one, I'll give him that, but all the bluster rings rather hollow. Maybe I'm too cynical, I don't know.
