The problem is how disjointed everything is. Skyrim and Fallout, I can literally walk across the entire map. I can run into a random plot, some fun environmental storytelling, anything really - there's no sense of discovery for a game so vast as Starfield. Everything is a known quantity which is why you can fast travel to and from basically every area.

All these other functions built into the game are superficial and/or incomplete at best. Ship building is basically pointless, as you can carry a massive crew in a tiny freighter, regardless of crew capacity or passenger capacity of your vessel. Modding weapons is more or less the same as it was in Fallout 4. The environments that are available to explore are all dead with fuck all, and all the tunnels and mines are filled with the same bullet-sponge spacer enemies. You would think with smaller, chunked zones we'd have some very detailed environments that make use of the fact that they are relatively small spaces, but instead everything is truncated with a loading screen and entirely lacking in depth.
