I'm playing on normal diff and it is becoming far too redundant - it's annoying to clear a new area and then get bulldozed by an asian rhino in an area where tapirs are. My only problem with FC4 are the instaspawn enemies that just magically appear from nowhere and take your health to 1 bar. The new gameplay options such as riding elephants, etc are creative and inspiring.
Even for console, it is superior in it's colors, textures, and richness in the environment. The Youtube posts really did the visuals in this game justice. Superior graphics w/ detracting random spawns
