OK, let's face it :
1 - The AI must cheat if it is to stand a chance.
There is to much variables in this game.  An AI will never reach the level of a human player.  That's why AI are so good in chess :  There is not much variables.  It is easy to implement routine to make an AI very good in chess.  Do you thing there would have been a challenge in Civ2 and MOO2 without cheating ?
2 - Malfador must still fix the AI.
It must stop doing stupid things, like : 
 - ignoring minefields, 
 - ignoring human player colonization in area of influence
 - making suicidal attacks (that's not hard to implement !)
 - Not using the latest technologies (ECM and sensors on attack ship, etc..)
 - You all know what I am talking about...
AI must be made #1 priority.
Is it useful to add new feature (ex. Drones) if humans are the only one who are going to use them ?
Multiplayer is way too long for most players.  Anyway, is it fun playing with 2 friends and 10 AI if all AI's are just waiting to be invaded ?
As for Talemn and all others doing Mods :  Keep up the work, we will get there someday !  And please share your wisdom  
 
Malfador :  Congratulation anyway ! considering the resources that you had to make a game, it is one good game system.
