Quest for Conquest is a 2D caravan management game, where you play as the leader of a ragtag caravan. Travel around a fantasy land where 4 different cultures have merged, but not always peacefully. Disarray is spreading through the land, and the ruler is doing nothing about it, so maybe it's time to replace them.
Asking politely most likely won't do the job, so you're going to need an army if you wish to take over the capital. But remember, this is going to be a dangerous journey, so you should always think carefully about the choices you make. It's hard to be a leader if you, and your troops are all dead.
