Same subtitle font, means no bit change is done. As for the graphics, just like Far Cry 4 was like a retexture of Far Cry 3, Far Cry PRIMAL is a pretty much small retexture of Far Cry 4. The gameplay is changed a bit. The whistle command to tell your pet to kill that turd actually existed in Far Cry 4. When you play as Kalinag in Yogi and Reggie mission, you can command a tiger to kell your enemies. The new thing is the spear. The fur does not move at all. Dunia Engine requires more change for this to be a next-gen game. Far Cry 4 had the same sounds and animations of Far Cry 3. Take animal skinning for example, knife sound was same, just the animation was sped up. Loot chest looting sound remains the same. There's nothing changed but only few things added. I would buy if Dunia Engine undergoes a complete change and the fur moves as in Far Cry 4. I say you again, do not make it a copy of the previous game like Far Cry 4.
