Good: Altarians, Drath, Iconian, and Torians
Neutral: Arceans, Humans, Krynn, and Thalans
Evil: Drengin, Korath, Korx, and Yor
The Thalans in DA were great for production due to their hive special ability but in ToA they get off to a slower start since they can't start off buying factories.
The Yor get off to a good start since they have some great one per planet improvements, low maintenance factories, and several economic boosting techs. However, in a long game without tech trading or stealing they will fall behind economically since they can only place one 25% and one 10% boosting economic planetary improvement; where other races can place as many 25% boosting stock markets as they want.
The Aceans when played by the AI don't expand more due to their lack of engine techs. I'll have to play to see how a human player can overcomes this.
So far for long games I like the Humans best but I've not played all the races in ToA yet.
