Loking for a game more or less similar to Banished, something with basebuilding that is not focused on combat.
Any ideas?

ANNO series? The older the game in the series, the less combat focused it is.

Children of the Nile is also nice, though it has limited combat.

Then, there is the Tropico series. Combat was automated (and very nicely so) until Tropico 5. Now, it is too combat heavy for me. And, in the older Tropicos, ppl's simulation matched the GUI as in Banished - another thing abandoned in Tropico 5...

However, I am completely with you, there are to few games like Banished out there, that get by without any
combat.

(Btw, I think there should be a sub-forum where can talk about games : https://www.gog.com/wishlist/site/a_betterstructured_forum - gog is about games, right?)

I have heard people call Planetbase Banished in space. That one has mixed reviews though. And there is conflict. Well, sort of. Sometimes there are criminal elements that can come with those trading ships and you have to build up a security force to handle them.

Might be worth checking out an episode or two of a Let's Play to form an opinion.
