And then you have the whole thing with The Maw, where people complained about the "deleted scenes" being released as paid DLC. I kinda see their point there, too, though I don't think the developer had bad intentions... as here. To me, paid DLC is kind of a minefield. And I agree, expansions without patches are just a way to bully players into getting the expansion to get the fixes -- hence part of my practice of ensuring that all of the fixes, interface improvements, etc, are always free to players of the base game even if they are "part of" an expansion. People don't like feeling like they're being shook down for money, and I don't want to feel like I'm shaking people down.
By contrast, even though the pool of AI War players has grown an insane amount in the last week, it's still incredibly tiny compared to the vast pool of strategy players out there. That's much more potentially lucrative, and not ethically dubious, so that's one reason why I'd want to stay away from paid DLC unless I had no other options aside from closing the doors -- in that sense, it would almost be a way for existing players to "donate" to Arcen, and get something in return. But that's the only context in which I'd be very enthused about doing it, the more I think about it.
