For a few seconds, this was soured to me. "Why do they need more, when they had all that initial money?!?"
But I... actually really like their explanations.
For one thing, I think the thing that helps modern game brands actually take off as more than 1-hit-wonders, if assuring something about them can cross the bridge of simply being "Diehard fan fun" into something massively recognized. If additional funding can give MN9 the kind of content it needs to feel less like a simple "tribute to games of the past", into something more fully fleshed out and budgeted, than awesome!
Second, I love seeing the aspirations towards an Animated series. Things like Captain N, US Darkstalkers, Street Fighter, the old MK cartoon, Super Fighting Robot MEGAMAN... they all helped those properties grow larger than their games along ever could. As a Megaman fan, I think it's awesome to see early consideration for trying to make MN9 into a long-lasting series. I wish SNKP would try adding life to their brands in such a way again! I'd love to see Dust: AET get an animated series (isn't the series based on Noggy's desire to make an animated movie?).
Third... I like Kickstarters giving a chance to more people to get a special discount, and to be able to get in on a KS they may have missed. If the Wakfu BlueRay set opened again, I might be able to get onto it this time, didn't have the funs back then!
Kneejerk reactions might be a bit negative, but if one thinks it though, this ends up simply meaning that backers get an even more polished product, and pay nothing more for it, unless they wanted to. It's a win for everyone involved, really.
