We hear this question a lot, and our answer is pretty straightforward: We wil probably want to come back and take another shot at the Endless Legend gameplay some day. But right now we don't feel like we have learned and progressed enough to make a real EL 2.0; if we were to start the project now it would be more like an EL 1.5 (and we don't think that would be fun to make or fun to play).
So eventually, yes, I think we probably will make another one. We just want to try other things first, and learn a lot more so that it really is a 2.0 experience.
Sorry, that's the best answer I can give!
