I just think it would be kinda awesome if from now on, each new Far Cry is a completely new setting.
Haven't new Far Cry games always introduced a completely new setting? Far Cry: Pacific archipelago, Far Cry 2: African plains and jungle, Far Cry 3: A massive island in the Indian Ocean, Far Cry 4: Asian jungle and mountains (Kashmir), Far Cry Primal: European jungle and mountains. Geographically there is the Americas and Australasia but how distinct are they from what we've seen? Plains, mountains, jungle, coastlines.
While Earth has hugely diverse ecosystems and jungles and forestry is highly varied, in game terms one bunch of trees is much like another: they burn, are good cover and an obstruction to your vision. I think that's why Ubisoft went to a different time in Primal. It gave them a chance to do somethigm radical in terms of weaponry balance.
What setting(s) do you think would work well - or appeal to you?
But what about people that's bored with the formula? I'm bored completely with far cry and AC formula.
With regard to Primal I would suggest you ask yourself what is it about the Far Cry formula that bores you, because they've changed a bunch of things. It's still unmistakably Far Cry but it's also different. I checked out of FC4 after about 10-15 hours, I'm 25+ into Primal and having a blast. I often find that I've waited 2 hours because I was just messing with the enemy and its the kind of game that gives you a bunch of tools (figuratively) to have a riot and it does a great job of making you feel über powerful one moment then completely vulnerable the next.
I'm definitely tired of Assassin's Creed. I loved Unity but Syndicate did't look different enough so I skipped it - maybe I'll pick up cheaper later in the summer drought. If I get the urge for Assassin's Creed I find myself returning to Unity and Black Flag. I'm interested to see what they do with their refresh. I really hope it isn't just a reboot.
