I hope they really add in a new style of gameplay. I am OK with reusing assets from FC but please don't be ice age FC without guns. There is a chance here to really make a good hunter/prey style game, stealth, resource management, camp building, etc. In depth inventory management and making traveling precarious and perilous. No huge map to unlock easily enough with towers and enemy camp #24 around the corner.
Let's have some good melee, TONS on animals, tough survival aspects and "boss" encounters really challenging and rewarding.
