I have at least 100 hours in the game, and I have to disagree with you. There's a surprising amount of variety in the creatures and the world generation.

I spend a lot of time building / designing my base. In that aspect, the enjoyment of the game is limited only by my creativity. I've definitely got $25 worth of entertainment from it. I will say, though, it is more fun if you have others to join your squad.

It's vastly better, imo, than Starfield. That was a game which really let me down -- I wanted Skyrim in Space, but I got 1,000 planets with the same cookie cutter quests on each. Or a team member saying something like "I can't believe we're the first ones to set foot on this temple" when there is a randomly generated outpost plopped down right next door.
