I already think the Kickstarter community expectation for a Linux version is a waste of time and money (yes, feel free to berate me) and an editor is another expense I'm dubious they can afford.
I pledged for the characters and stories of Chris Avellone and the design mechanics of JE Sawyer and Tim Cain (et al). That's my first interest. I can get community content from Skyrim and other places - I want content from Avellone.
I understand and personally, I don't care at all whether they ever make Linux, OSX or DRM-free versions either, perfectly happy with Win7 and Steam DRM. However, official mod tools would mean a game I can play over and over for years and also enjoy making my own content.
