How should I make a The Sims kind of Game?

So I want to make a game similar to The Sims. The problem is how should i make the controls of it?
I made a brand new pawn so i can move around like an RTS camera, but i can’t control the character. And if I do all these things with the custom pawn and with an AI i must do everything in the level blueprint and of course if its a multiplayer only one AI will spawn. And I have no idea how should i make this. Tried a few things and nothing worked.

Hope have some idea to tell me :smiley:

Have a nice day!
