Is The Sims 4 mod available for sale?

Hi @SimsCDR,

EA don't create mods. Mods are player-made content that you can add onto the game EA has created. Maxis does support a framework in The Sims 4 that makes it easier for you to install and use Mods, but we doesn’t pre-screen, endorse or specifically support any particular Mod. You should use Mods with caution and understand there may be risk.

Another question is  can player sell the mod that player create?
