A few years ago I purchased GalCiv and GC2.  I played them both and enjoyed them, but I quickly became bored with them.  I've not played now for years.   It took me a while, but I soon figured out why;

There just aren't enough strategic decisions to be made with the ship building / combat strategy.   Every battle is simply a game of rock/paper/scizzors.  (Lasers, misiles, cannons) 

Wouldn't it be nice if we had more variety avaliable in our combat.   Ultra long range but slow fireing weapons, fast hard-to-hit ships with weak weapons, weapons with effects like slowing the enemy ships, splash-zones, cloaking, decoys, armor erosion, tractor beams, etc.   How about some obstacles too, like debris, asteroid fields, plasma clouds, radiation belts, etc. 

Of course, the ability to influence combat would be quite appreciated as well.   Even if it was simple commands like; close combat, long range, target ship, engage speial item, etc.  

the game just lost depth for me when I realized that the funnest part of the game - combat, was, well, shallow.

I am hopeful that maybe a future iteration will allow for more.
