So basically, with the D:OS 2 Kickstarter, every other factor should be ignored except the Linux version of D:OS? No mater what benefits could be expected starting it now, and no matter what conflicts or problems there could be with a delay, a separate group of people working on a different game should just wait?
If there weren't a target release date for the Linux version, and it wasn't fairly soon, you might have a point. As it is, the D:OS 2 Kickstarter is not going to delay the EE release, and delaying the Kickstarter would not speed up the EE release.
Planning is part of development. And yes, that is where the issues with Linux started, as described by Lar in a forum post some time ago (a topic which you posted in).
Rather than paraphrase my post incorrectly to label it as "borderline insulting" you could try addressing the content. Or ignore it; either way isn't going to change anything at this point.
Larian did not try to "cut corners". It was explicitly the plan from the very beginning to start the Linux version after the Mac version was finished, and development of the Mac version had been halted and only resumed once the Kickstarter reached its funding goal. At the time Larian wasn't sure if the Mac version would catch up by the game's release. Being up to that point a Windows only developer, Larian was of course focused on the Windows version, and never claimed otherwise.
