Far Cry 1 - incredible for the time. It was the Crysis of its day. Not perfect gameplay wise, but huge world to explore.
Far Cry 2 - quite possibly the most vapid, dull game I have ever played. "Go assassinate some one" and "Drive around in circles trying to stop a convoy" - repeat to fade.
Far Cry 3 - It's supposed to be a FPS, not an RPG.
Far Cry 4 - See Far Cry 3. Just more of the same.
Not exactly my fave games.
Having said that I got The Crew for nothing and had fun hacking around in the grass before realising it was locked to 30 FPS.
Their best game ever was South Park The Stick Of Truth. I am praying they don't wreck The Fractured But Whole.
