I see a few different possible paths:
Cottage Economy: Happiness is vital here. We research calendar and monarchy to increase happiness. Then head for liberalism, education and printing press.
Great Library: Polytheism, Literature (Music). Pretty straigthforward.
Music Great Artist: Drama, Music. Not very rewarding, not very expensive either.
Exploration: Compass, Optics, (Astronomy). Set out to meet the other continent. Not really a priority IMO, as our continent is big enough for the moment.
Constant Warmongering: Monarchy, Feudalism, Guilds and Banking. Keep fighting wars, adopting mercantilism to keep the economy afloat. Going straight for domination.
