I know one. Bioware.

If you're referring to NWN, then yes, that would be one. They made a game and worked closely with the moding community to ensure their game did what it was designed to do: be a platform for D&D enthusiasts to make their own custom maps. It was critical that they kept the people informed about what they were changing to try and foresee any problems it might cause with modules that already existed created by the fans. KotOR2 is a stand-alone, non multi-player game with absolutely no moding support. It isn't prudent or necessary to make sure that everyone on the boards knows that we fixed something behind-the-scenes that will never affect them directly besides improved stability. We don't need to post on the boards saying that Installshield rejected an erroneous line of code added to redirect the auto-patcher to the proper website. We're not going to come on the boards and tell you exactly what happened as it happens. Frankly, it's an internal matter and we're trying to get the patch to the public as soon as possible.
I can assure you that with a community-driven game like NWN2, members of said community will be (and have been already) active contributers to the project since it is a game for the modders and any changes we might make at a later time might render their modules useless... something we want to avoid.
