Not every game needs to be a epic, 200 hour long game where you just run around and kill stuff for shits and giggles. Sometimes its good for the game to be more contained and focus more on the world, story, lore and world building. Plus, from what I heard, The Outer Worlds is going to be a franchise. Microsoft is quite pleased with the games success and praise and now that Obsidian is going to have the funding of a AAA gaming studio they are going to have more funding to put into The Outer Worlds sequels. Expect The Outer Worlds 2 to be grander in scale.
