There are more older higher demanding games ( Witcher 3, Sainthrow, Skyrim) that are available on the switch. Therefore, the Sims being a less technical and less graphically demanding game, it should have a version on the switch.
The community manager has even tweeted that they have no plans to release the game on switch at all. It makes no sense as really its a win win situation. They get the revenue and the fans get a game they love on their preferred gaming equipment.

If you love using the Nintendo Switch and playing the Sims 4, then well, sign this petition so that gamers may possibly have this wish come true. We just want the Sims 4 on our preferred gaming equipment.
