The boost jumping and wall riding mechanics in BO3 add a lot of variety and frankly more skill to combat and movement and make it a lot more fun in general. The Specialist classes that give you some sort of upgrade or extra weapon when you get a certain amount of points makes combat very unique and more interesting in many cases. A lot of the weapons seem really balanced already, except for 1 Shotgun that is fully auto and has a lot of range and damage. Ghosts had a lot of imbalanced weapons and everyone gravitated towards them more. And of course BO3 has the classic Zombies mode that everyone loves (still haven't tried it yet in BO3). It's way better than the Aliens in Ghosts lol

	On a side note this is also the first shooter I've played on PC in a long time so I'm enjoying it a lot more because I'm getting used to keyboard and mouse again, and that's fun.
