Marvel's Avengers

Marvel’s Avengers is a third-person action game from Crystal Dynamics about a team of super heroes. The story starts after a disaster at an Avengers Day celebration, which forces the heroes to come together again. The Definitive Edition includes the later content updates.

In the campaign you play different heroes: Hulk smashes everything around him, Thor and Iron Man fight at range, and Black Widow is fast and sneaky. Each has their own combat style and a skill set that opens up as you level. The campaign is built so that it can be finished solo.

The story takes about 12 hours, and a 100% run about 105 hours (according to HowLongToBeat, counting repeatable missions). A month at 2 hours a day easily covers the campaign. To be honest, the co-op missions need online access, and the rental is offline-only, so the available part is the single-player campaign.
