It is my opinion that this game is lacking a lot of polish and right now has very poor cpu utilization.
Its quite grungy. Remind's me of Rome 2 on launch, which is not a good comparison. I'd really like a left/right tab on my shipyards the same as colonies,. I have all of the yards shut down most of the time, so activating and queuing builds takes for ever with 5 yards all over the place.
The rest I'm not to fussed about as it its a turn based game. but it gets really grindy and tedious late game. If I could hot key up screens for ships, colonies and planets. I really want to know which ships are in which groups. Putting a frame around each fleet would be excellent.
Being able to group planets geographically would also be nice. As has been said, its a nice enough game, but the interface is kinda awful at the moment.
