Marvel's Avengers - The Definitive Edition is now on sale on Steam and Xbox for 90% off. It's important to remember the announcement that sales and support of the superhero action/adventure ends after this month. However, this post explains what parts of the game will remain playable after that in case you want to get in on the bargain:

As we’ve previously announced, official support for Marvel’s Avengers: Definitive Edition is ending on Sept. 30, 2023, and the game will no longer be purchasable on Steam. However, we wanted to reassure you that while the game will no longer be for sale, the game will remain playable for owners largely as it is today.
