Really big fan of functional jetpack nerf, makes you actually build your ships and base to be walkable.
Usually we play with Aryx, defense shields, nano build and repair, fsd supercruise, and hacking computer for warfare.
Resource nodes, pipelines, and scarce resource/se world gen for economy. Makes you travel around, colonize planets, and ship resources, but allows you to set up infrastructure over time to automate most of that and have a consistent resource supply.
I'm interested in an oxygen nerf and 3rd person nerf to add even more building constraints, but I think that's too much for most others on the server. It'd be cool to force smart pressurization practices and camera usage/battle bridges, the same way jetpack nerf forces walkablility.
