    Seven Kingdoms: Ambition

    Seven Kingdoms: Ambition

    An enhanced version of 7K:AA (Seven Kingdoms: Ancient Adversaries).

    Seven Kingdoms: Ambition is a real-time game of epic strategy and empire building featuring economy management, warfare, and intrigue. It is an updated and enhanced version of 7kaa (7K: Ancient Adversaries) featuring numerous fixes and improvements. https://discord.gg/xJs99xK38G Begin with a single, modest village under your command, and an entire world to be conquered by force of arms, guile and persuasion, or whatever other means you choose. Wage open warfare on your rivals, or forge alliances with them. Send spies to infiltrate their ranks, or hold them back to guard against your enemies' prying eyes. Mine ore and manufacture goods, then build markets and establish trade routes to bring gold flowing into your coffers. Have your scientists research new technology, or turn from science to the mystic arts, and seek the ultimate power: summon the aid of the gods! A more complete list is available on the wiki: https://sourceforge.net/p/seven-kingdoms-ambition/wiki/Features/
