I already get all of that with GWX and NYGM.
I'd probably pay up to $60 for a "Complete Silent Hunter" which included a "whole war ocean" and was compatible with all current SH3 mods/tools but also included SH4's improvements. And a cloth map and THICK and useful manual!
But I don't think we should pay for bug fixes at all and content we get from the community. All Ubi needs to do is give us a robust and extendable framework and 40 hours of fun, we'll take it from there.
