I've downloaded the game just before work...but have not (yet) have had a chance to play.
Are there apparent issues, bugs and concerns? Sure.
However, I have confidence in Stardock working through these. Yes. They stand by their products. They improve their products. And any software not made for an closed system (e.g. Apple) is going to have technical bugs. and other bugs--these things do happen. Its simply the nature of the beast. It doesn't mean that we eschew reporting the bugs, either (politely, rather than being drama queens).
I expect, in time, as good or better things from the Elemental-verse as we have received from the GalCiv-verse.
