A few comments from the stream....
1. I vote hex maps...
2. make the mini-map zoomable... Hex-shaped versus square, to match the galaxy, this would make sense??
3. Starbases are a cost after 4, nerf the cost based on galaxy size please... The larger the galaxy the easier it is to make more starbases... Please.
4. When will some minor races be added? I know major races will be coming in slowly, what about minor races?
5. Paul stated that one may be able to get bonus's for invasion and limiting to a 1 time reward or such. Why not offset this stating just invaded planet/colonized no bonus's for invasion for x turns (x) being random could be as early as say 5 turns but could be as many as 50. Or even make it on a random, it may give you a bonus but may not depending on x being a percent... There comes a time where you can't get any production because one has no population on the planet so exchanging planets between a friend becomes less profitable.
6. Maybe do a contest with the founders for a minor race for the game or DLC? Have them put in suggestions and then have Stardock pick from a few and vote on? This is a silly suggestion but, I thought worth putting out there?
