What do you look for in a mod that keeps you playing time after time?
Also what mod addresses those particular aspects? or better then any other mod?
(Bonus points if you direct myself or others to where you can get the mod)

For me it's a pretty long list I guess, I'm very particular.

Increased movement points for all units, especially for agents.
Increased number of settlements everywhere.
Altered build times and costs-should match the pace/cash flow of the mod.
Any added civilisations are welcome, as long as they are properly implemented.
More reasonable diplomacy.

That's all I can think of so far, and the mod I've played the most so far is Darth Mod 1.4D.
Increased agent speed, rebalanced unit stats, building time/cost changed.

Your turn.
