As many people mentioned here; the game requires multi-level thinking. It also has incredible atmosphere. I might be biased (though not a die-hard maniac of old games), but it aged well - even drum-and-pie miliary tunes sound better in this ancient version... I also played the remaster, which, apart from graphics, is worse in every aspect; especially AI. The only reproach against Colonization is that starts can ne uneven; sometimes you have a very small chance to survive whatever you do, sometimes it gets incredibly lucky and you snowball... An experienced player can recognise an overly (un)lucky game and start a new one to get a properly thrilling experience. Otherwise, it's a real treat.
