I didn't take the time to read every reply on this thread or get enough money together to pre-order TA so it may have already been suggested/implemented: How about an option to give all races and equal tech tree? For instance, I play Star Wars: Galactic Battlegrounds still and it is really a lot more strategic when you and the computer have equivilent acesse to technology.
I also think that more major races should be added ... so that there are more AI options to face.
Fist I agree to his post. With the Gigantic Maps add another race or two, Have one of the races incorporate all the techs from all the races in the game but be handicaped somehow, maybe by a low reproduction rate or low moral or something.
Here are a few more suggestions from me.
-Like JesanFafon said, allow you to roll back the tech trees to the origional, but play with the new TA features.
-Add a few more minor races to game, with the immense galaxy size I would like to see an option for more minor races.
-Get a score boost or decline depending on Tech rate, very slow tech rate for instance will make for a slower game or faster tech rate normally makes for a faster game. Same thing with more or less habitable planets can change the normal length of the game. I think you already have score somewhat based on size of galaxy.
-I'm sorry if I had this in from before, but I'm in a hurry now, Add an option to increase or decrease the number of specialty planets.
-fix memory issue (just had to throw that in

leading to next request)
-increase number of star for immense galaxy (right now it seems about the same as gigantic just more spread out)
Thank you.
