I very much like the idea of a new generation of turn based strategy games, thus I'm the happy owner of TA since it's release date.
Thank you for putting 3 years of effort into the game! It shows.
Now the only thing you need is a strong PR campaign to get the sales up

I do recommend sorting out the manual and training videos first, most people I've spoken to needed some pointers to find the features they appreciate. I can completely understand this, being your first game, I guess you guys have been dreaming TA for the past 3 years, it's hard to move to the mindset of someone new to the game.
All in all, I think TA has the potential to become a hit for it's target audience. And I'm hoping to be able to assist you guys to polish off some rough edges, as respect to all the effort you put in it!
By the way - I hope I'm allowed to put this here - did you hear about what Brian Fargo, the former CEO of Interplay (RIP) did with his Wasteland 2 project?
