It's a flexible funding campaign, so they're gonna get the pledged money no matter if the reach the goal or not, and I'm sure Shaq can reach in his pocket and fund the rest himself if needed.
For me I'm just waiting to see actual gameplay footage before jumping in. I'm somewhat hyped though, it seems like it could be cool, and it's sad to see all these people calling it crap solely because it's a sequel to a bad game that was made TWENTY YEARS AGO. I mean, come on, give it a chance.
