Pinstar
Ringtailed Regent
You know the type. Not enough hammers for a good wonder/military city. Not enough commerce for a good science city. Not enough food for a GP farm. No resource tiles in its BFC to write home about and maybe a few dead tiles to boot. Assuming the player knows not to bother with these city sites in the early game, what is the best mid/late game use for these "meh" cities?
