I picked up FC3 again shortly before getting into FC5 - I played it for about 2 hours but couldn't really remember where I was in the story. I got to a point where I was fighting a big nightmare demon in front of a temple and died a few times and haven't gone back.
I might go back after FC5 though - I was trying to stealth my way through FC3 and I think if I take the more guns blazing approach I have been doing with FC5 I might have more fun.
As for Primal - LOL, I know but I am more interested in it for the survival mode and setting. I kind of wish there was a survival mode for FC5. Best of both worlds - more realistic unencumbered gameplay and some of the best explosions I've seen in a game.
