While I have a bit of experience in such things, unfortunately I have no timeslots left.
However, here is an advice:
the game has a lot of turns and if you want to see the end or at least make it into 1890's your greatest concern is to get the game going at all. It is not the game mechanics that you should be concerned of in the first months of your common journey but the group of players. Decisions ingame should be taking relations offgame into account.
Playing a long game means that there are very little decisions that are fatal gamewise, but a lot of decisions have the potential of collapse offgame.
