[Q]

Playing the demo I over all like the game but there are some aspects, that need improvement IMO:
1.) Limit the construction per turn for a fabrication complex. It seems odd to be able to produce ten bombers, fighters and tanks in the same location just in a turn.
2.) Research should not just be paid but as construction you should need specialized facilities that give you new technologies after a certain time.
3.) The biggest problem IMHO is the combat system. One unit should never be able to kill more than one unit in a single shot and units should be able to move individually. And I really hate this squared combat grid. It is just ugly and spoils the nice aerial landscape pictures. Let the units move freely with colored circles indicating range of fire and movement. As others I strongly suggest an auto-resolve possibility for combats too.
4.) The AI has to be improved and there should be a team mode AI against human.
