What are the best RPGs?

Base building is a way that the player can collect components in the world to then use them to make their own base for equipment and supplies. There is also an interesting aspect where the player can attract NPCs in the game to their base in order to create a settlement (basically a small town of people). This can only be done in particular spaces in the game though. The rest of the base building mechanics can be used anywhere the player wants and in any style they like. If you want to build a floating base that only you can access, this can be done. Want to build a giant towering structure that goes as high as you like, you can do that too. Really there is very little limiting the player from creating anything they imagine for their base. This can make for a solid distraction from the main story of the game as the player can sink as much or as little time into it as they like.
