Now, I liked messing around with Anno 1800 when UPlay had it’s free trial of it’s game pass thing. I played a bunch of the campaign and maybe played some random map (don’t recall). I’m just not a huge fan of the formula. It’s a little too…clean? They both share the same basic principles. Harvest a resource, turn it into something better through some production building and use it to keep people fed / happy / build something. They both have higher tier citizens that require another resource (Anno’s is a bit more involved).
Anno maybe makes the player make efficient use of space, but with the teleporting goods through warehouses it doesn’t require the player to make efficient transportation of that resource and that makes it a bit too simple / uninteresting. That’s not to say Anno is always easy. It can be a bear to squeeze something in or have enough space to produce the resource on the island with all your houses on it. It’s just a problem I find a bit more tedious and less interesting to solve - start bulldozing, moving production to another island, ship the resource over, etc…
Anno is gorgeous to look at though, especially those fields of wheat. There are probably more things to build and maybe things to fiddle with. I find the AI personalities annoying, along with the campaign story, but playing vs the AI can make the game more interesting. I think The Colonists may have an AI opponent but I’m not sure.
It’s also possible that one may tire of The Colonists before Anno. I tend not to play this genre into the ground so it’s not a big issue for me.
