The Lord of the Ice Garden is about four scientists who become gods warring against each other
I am nearly finished with Children of Strife and was reminded of this one weird board game I played over 10 years ago.

>The world of Midgaard, created by author Jarosław Grzędowicz in The Lord of the Ice Garden novel series, is inhabited by a race very similar to humans, filled with magic and for a reason stuck at the cultural and technological level of medieval Viking world. The arrival of scientists from Earth disturbs its fragile balance. The power gained by controlling magic changes the scientists – they become possessed by the lust for making this world better. They become gods, who are willing to sacrifice any life, except for their own, of course, to accomplish their – great, according to them – ideas.
It is a apparently a popular Polish series that was never adapted into English, but the parallels are striking.
