It has been awhile since I have posted hints, because of a final game placement.
27: Starting off with a big empire is fine and dandy, at least until possible revolutions happen. You could lose half of your empire in an instant.
26: Having control of the sea, expands trade massively. Having control of land, just looks cool.
25: A massive magma titan wants to kill you, and everything in its path.
24: One of the most pivotal games of all open world games. This game features 3 factions vying for control of the continent.
23: Hacking and slashing is back, this time with a 4th faction.
