Red Dead Redemption 2
Red Dead Redemption 2 is a Western-themed action game that is honestly amazing. It's a free-roam, cowboy, Tarantino movie dream come true. It's nicknamed 'Yee-Haw' Skyrim, because of the huge array of side quests, weapons, and the amazing level of detail in the characters, and the missions. If you've ever played any games similar to the Assassins Creed series, Skyrim, or even the Batman Arkham Knight games, then you'll have no problem with Red Dead Redmeption 2.
Although, as amazing as everybody here will agree it is, there are some flaws. It's depressing and can be kind of slow sometimes. The developers did an amazing job trying to immerse the player in the game and make them think that they are in the wild-west, but they may have done an almost too good job at it. Showing that the life of an outlaw cowboy in 1899 isn't as glamorous as a Tarantino movie might make you believe.
