Im running the latest version of ToA, and there are a Lot of "improvements" made to the AI and the game in general. The biggest difference between DL and DA and ToA is the introduction of unique race tech trees in ToA. They are a lot of fun, and allow you to play a lot of different ways and introduce a lot of variety to the game. HOWEVER, the AI still does NOT A) Build planets correctly or effeciently; and
Protect transports and make coordinated, well executed attacks.
***If a human player were to play like the AI, it would never win a game. ***
If you like this game, I'd definately get the expansions for added replayability and variety. Its a good game, just not great, yet
