We need more pirates!

The PBW versions are filled with extra features that the AIs simply can't handle. Extra fun for a PBW humans-only game, though.

You want a non-PBW version, like:

There should be some stock AI files in there, but I suggest copying some races from the TDM modpack, and running the AI Patcher on them.
The AI patcher will convert the races from stock to P&N settings so that they will build ships that can actually move and set up their races so they can actually colonize.
