I'm actually fairly pleased with the QA behind the stuff Paradox has actually developed relatively recently (at least, it seemed CK2 had a pretty good release, and the game as it is now is great), but I'm more cautious about the stuff developed by someone else and published by Paradox. Magicka, Sots2, etc. That doesn't mean a good game won't eventually emerge, but I don't want to drop $10 on something that's a total bugfest. Even if it turns into a better game after that, the first impression can be a negative for my future enjoyment of it.
