Does DA go into a separate directory?

Da will install to the GC2 folder, but each game can be played separately.

btw. Glad to see you got your email problem fixed.  

Yes, thanks, I'm trying out my first game now with a custom alien race as one of the opponents. I like the wider range of ship designs (the automobile inspired hulls are great), still trying to figure out all the new potential strategies with mining, habitable planet research, etc. Seems the first Major race I encountered was my custom design, so we'll see how that goes.
