So you want Volition to post publicly SR2 source code thinking the community would fix the game?
We don't even know at what state the current build of the patched version is. What if it's even broken than the original release? Who would fix it? We have a bunch of talented modders in the community but I don't think they would do that. The best option is to "hire" some people to work on the patch from the community. That's the best option imo.
