IMHO yes. It is among my favorite games of all time.

The plot is of course nonsense (all far cry plots are garbage), but the core gameplay loop is tight, the shooting feels good and there's a diverse arsenal, you get a large selection of colorful sidekicks and animal companions, the most annoying mechanics of earlier titles in the franchise were fixed or removed in 5, and the entire campaign can be played coop after you escape from tutorial Island.

It doesn't take itself too seriously but it's also a internally consistent rural Montana simulator. Stealth mechanics feel great (subjective ofc) but more aggressive strategies work well too. The base game has plenty of content and goes on sale frequently.

It was everything I loved about FC3 but more of it and bigger and polished to a radiant shine, with a kitschy rural US setting.
