OP Mod-lists:
Gameplay & UI Beauty & Texture Updates Pawns - Hair, Guns & Gear Initial Start / spawn in here if interested. The easy way to play an Island is just to use the ‘Biomes: Island’ mod, but I personally disliked some sweeping changes they made to water and weather effects.
Instead, I used Map Designer - they have an option toggle to generate a ‘Perfectly Round Island’, regardless of map tile selected. I also used Better Map Sizes when selecting my tile on world spawn to reduce the size to about 90x90.
Finally with the map being so small I used Change Map Edge Limit to remove the restrictions on building at the map edge.
My colonists live an idyllic lifestyle in the sun, with Parties, Orgies and Festivals a regular occurrence. Our chief exports are Yayo, Sushi and Whisky, all sold directly to Hospitality guests.
Playing on a tiny 90x90 map was a huge challenge and for the most part an engaging one. Every resource and caravan mission counted, we collected hundreds of limestone chunks!
Downside was having enemies spawn literally on top of you, with entire mech clusters crashing INTO your base. Wild animals get desperate to eat your crops (or pawns) real quick. Building 30% of the base on bridge support vs enemy explosives is pretty worrying.
PSA: the trippy water can be fixed by ‘hiding’ the updated water images from your terrain mod (if interested, I can dredge up the details). I used the trick in my post a few below. In your case, I agree it adds the perfect ambience to your island!
