One of the techs at the academy I really like is political science, since it makes gaining influence so much easier. yet I think it would both be nice, and rather helpful if we altered it to where it also increased population gain through building up ports as well.
maybe something like,
each level gives a 1% increase or the like along with the influence bonus.
on the list of things id like to see added, this is pretty low, and I wont mind if it doesn't get added, but I think it would be a nice addition.
