My favuorite Sims game is The Sims 2, despite corruption problems (The game is already corrupted when you first installl it.) and lots of limitations, then The Sims 4.
My perfect Sims game is Sims 2 depth, Sims 3 colour wheel, Sims 4 customisation and Sims 1 silliness. I dont want a full open world, because it lags the game, but you should be able to e.g.visit your next door neighbour without a loading screen.
Do NOT attempt to make Mateusz Grześkiewicz playable, move him into a family, turn him into a supernatural creature, or tamper with him in any way or form outside of his in-game designated purposes. Doing so will cause game corruption, fixed only by uninstalling and reinstalling the game.
