• Theme: The subject matter of a custom major need not be within the realms of possibility. We have magic majors, hoodlum majors, majors on how to be a ninja... no sense of reality required. However, whatever theme you choose must make sense as a major.

• Uniqueness and Grammar: Description, title, and classes must be new, unique, and interesting. They must also be double-checked for spelling and grammar. If you need help with proofreading, you can post a thread in the Creator Feedback Forum.

• Clear All Languages: Make sure to hit "Clear All Languages" before you upload, or your file will not work properly with non-US English games!

• Overwriting: Unless your major is specifically intended to overwrite a Maxis major, it must have a custom GUID.

• Skill Requirements: If you use BCONs to alter skill requirements, test them thoroughly before you upload. Incorrectly modified BCONs can cause game crashes, so test them.

• Custom Icons: They should meet the standards laid out in this mini-tutorial - that is; be the roughly right colour (if it's a single-colour silhouette), NOT be a random photo, and have a transparent background. You may use an EA icon if it is appropriate; the main purpose of this requirement is to ensure that the UI looks neat when your major is in use.

• Icon: You must include your major's icon, or a picture of it in-game.

• You must include in your post:
  • Major title and description, and class names.
  • If the major overwrites a Maxis major, you must state which major it overwrites.
  • If you used BCONs to alter skill requirements, state which skills are focused on.
  • The icon used for the major, as an attachment to the post. If you created your icon in a program which uses lurid pink to show transparency, put it on a white background; otherwise it wont look good to downloaders.
  • Majors require University. They are not basegame compatible. They do not require Nightlife, Seasons, or anything else. Tick the University box, and that's it!

For instructions on compressing your files into an archive, please see: Creator Guidelines: Creating Archive Files.

• Do not include multiple archives with the same contents - that is, please don't put your files in both a .zip as well as a .rar because some people only want .zip files. Choose one format.

• Do not double-compress your files... a .rar file inside another .rar file (or any other archive inside another) doesn't compress it anymore, and it makes it so we can't see the contents without downloading, and also just makes an extra step for the people downloading.

• The file size limit on MTS is 50 mb. If you exceed this limit you will need to split your archives. This should probably never come up except for large worlds for The Sims 3, or huge sets of smaller items.

• If your upload is rejected or marked as changes required and you're not sure why, ask in Creator Issues.

• If you're not sure whether your neighborhood is ready for uploading, use the Creator Feedback Forum to get feedback on it.
