Imo starfield has a lot of potential strictly because theres soo many planets you can choose to do mods on. Its proceedural vastness will give modders room to do stuff without overlapping with other mods.

Do i think Starfield is the best, far no, its better than FO4 to me, but worse than its 3d predecessors for FO/TES, but it leaves a lot of room for potential due to how much customization already exists in thr game.
