This should put a fork in this issue once and for all.
- Do not promote your Mods in a way that suggests they are endorsed by or affiliated with The Sims, Maxis, or Electronic Arts. This means you cannot use any game logos or trademarks, including versions of the plumbob, or key art designs to promote your Mods. You may state that your Mods are for The Sims 4 and/or for a specific game expansion pack.
- Mods must be non-commercial and distributed free-of-charge. Mods cannot be sold, licensed, or rented for a fee, nor can Mods contain features that would support monetary transactions of any type. However, Maxis recognizes that creating Mods takes time and resources. Accordingly, Mod developers may recoup their development costs via passive advertisements and donations as long as:
- Passive advertisements and requests for donations must be limited to the Mod website or distribution site, and not appear within the Mod itself.
- All users must be able to access the Mods in full for free regardless of whether they donate.
ALL USERS MUST BE ABLE TO ACCESS THE MODS IN FULL FOR FREE REGARDLESS OF WHETHER THEY DONATE...
Can't be more clearer than that? Something that we've all been saying since oh, day one.
