No, I don't think we strictly need a centralised planner, but we do need a
replacement for fstk, which is both an attack planner and a city-by-city
unit want function.

Greg has suggested a sort of statistical build manager for the AI in the
past, and this not a bad idea, combined with other input, to ensure that
we build a bit of everything. I have suggested a queue scheduler, and I
think I have the notes for this ... somewhere ... and I will try to put
those up on the wiki later on. But nothing is carved in stone yet.

Not really. It has long been the idea that fstk should die. However, the
bar to replacing fstk is really high, so fixing it somewhat in the interim
might be worthwhile.

I had a huge patch a while back which rewrote fstk to use pf, but I
dropped it as I and Greg decided fstk was essentially unsalvagable.
