I feel like starfield is an experiment in user driven content (mods) to sell a game. The issue with Skyrim is that there is really only one map, and before any map extension mod came out, there were so many mods out there that competed for space on the map. Even today, large world overhaul mods are constantly stepping on the toes of other mods. City redesigns are also a problem unless you’re really good at load orders and merging.
Starfield feels like each world is an open map, ready for people to start designing content: either a colony, a cave, or anything really. The story seems loose and open ended so that it won’t interfere with large collaborative content. It’s not a game they are selling, but a modding storefront. It’s like Skyrim Creations, but putting the horse (armor sold separately) before the cart.
You might be interested to know that there are several hardcore modding scenes, where the point is to mod the game for fun. The mod guides are updated every month or so and includes thousands of mods. It takes days to install, and actually playing is optional. In most cases, a new save is required every update, so modders keep an additional playable state if they actually want to play the game.
Lexy’s LOTD is my fav one, it’s only over a thousand mods, has very detailed instructions, and a very friendly community.
