Well, the third character DLC has been reached, and it's 1,000 over the bar. Still have another two days to raise 24,000 bucks. But it doesn't look like the Mane 6 team will get the Skullgirls engine at this pace. If it does break 625,000 I doubt people will want to raise another 100 grand for an "MLP turned non MLP" project. It was a sweet sentiment of the Skullgirls team, but expecting that much extra after the fans of the mane 6 project probably already putting their money down to help wasn't all too expected to be met unless there would have been extra content at reaching that goal as well for the Skullgirls fans.
