The last one was Far Cry Primal, which of course had protagonists, but were set in 10.000 BC, and was pretty damn awesome , especially with Permadeath and survival mode enabled.
Basically, its an open world game set in the stone age where you can tame saber tooths and use them as pets - I say again…its pretty damn awesome!
As for Far Cry 5 - I kinda hope its not zombies, although it REALLY looks like it. That just seems kinda lame compared to Primal. I know we should probably wait and see what the game is really like, but there are so many great options for a Far Cry universe that setting in what is, besides WW2, the most used setting in games, just seems…lazy.
