I only recently got the game and although I do love it there is ALOT they could work on. I was really disapointed in the depth of the game overall. Maybe I just expect too much from a stragity game after playing GalCiv2, but I feel like everything in Sins is just way too basic and easy, as well as the AI not good enough. My first game I jumped in on hard setting and easyly stomped the AI. Also having NO campain or real storyline what-so-ever is VERY lame. Also only 3 races?!
Basicly I feel like this release game is very polished but as far as depth it seems like a beta version. Dont get me wrong its a very good platform that could be greatly expaned on and thats exactily what I'd like to see.
1)Double the size of the tech trees - I really dont see many options in the tech trees, these could be greatly expanded upon to add some more depth to the game.
2)Larger maps! - at first they seemed large but once you've played the 'large' or 'huge' map more than once they dont seem very big at all. Id like to see some truely massive maps on an 'unrivalled scale' like the box promised

3)Add AT LEAST 3-5 NEW races - Only having 3 races is a major drawback to this game IMO.
4)Greatly Improve the AI - like I said I had no problem stomping on the hard AI in my Very First Game! Take some pointers from GalCiv and make the AI more engageing/challenging. Also more settings than easy / med / hard would be nice.
5)Expand the diplomacy options - the diplomacy in this game is extreamly limited. Some more options in here would be great and also some differant missions beside give $ metal crystal or destroy stuff. It just seems very repeatitive and trite.
6)For the Love of GOD add in a story!!! - Im so freaking disapointed that there is no story here at all outside of an intro movie. After I watched the intro the first time I was like sweet cant wait to find out what was chaseing them...still waiting cause its not in the game!! It seems almost like they released a 1/2 finished game.
