Super Luigi Galaxy is a game inside of Super Mario Galaxy. After collecting 120 Stars as Mario, you will be able to play as Luigi. Luigi plays different that Mario however.

Some missions in Super Luigi Galaxy had name changes. These changes are:

- Honeyhive Cosmic Mario Race is changed to Honeyhive Cosmic Luigi Race.
- Frosty Mario Cosmic Race is changed to Frosty Luigi Cosmic Race.
- Cosmic Mario Forest Race is changed to Cosmic Luigi Forest Race.

- Luigi is unlocked by getting all 120 stars as Mario, so it is impossible to get Luigi first, even using hacks.
