I don't think it was purely political, or at least I don't think that any rational, intelligent person who evaluated the situation would see a shutdown as purely political. Chafee himself might have closed it down out of purely political reasons, but lucky for him there were plenty of non-political reasons that would have led a more neutral observer to the same exact action. The reality is that video game development utterly devours money, and there's no way the state could have been guaranteed that they weren't just throwing more money down the drain.Going on from that I believe the State would have got all it's money back had it made the final decision on whether to further back 38S in favor of either offering further funds or holding off on killing 38S. I do believe the decision to close down 38S was a purely political move. Curt stated that he could have got outside investment if the State hadn't pulled the kill switch and I believe that too - it was probably the first time Curt was going to give up any considerable stock in the company.
In terms of outside investment, I don't think you can trust anything Curt says on that matter. There is literally no scenario you can imagine in where Curt would have said anything along the lines of, "The project is in a bad shape, we probably can't get outside investment." Which means that him saying that they could get investment is a completely meaningless criteria to use when evaluating RI's final decision.
