Presenting you
Cultures, a game from 2000 that I love very much even if it's so complex. I don't know why it's so hard to find videos on Youtube, but I did find some
gameplays in German
You play as vikings and the campaign is about their journey to discover new land, make trade and war, of course. You can even marry people, decide where everyone goes, what job they do, how to make babies, how to make stuff that will improve the life of your little friends etc. Basically it's a game that lets and teaches you how to live from the land, use available resources that don't regenerate and most importantly pay attention to a ton of details... that's why the game is slow, but really fun.
The game can be purchased from
GOG
. I've only played Cultures 2 for a short while and never liked it. Too many unnecessary changes, it kind of looks the same, but it isn't.
