Same! My buddy and I repurchased World at War for the original zombies that kicked off the series on Call of Duty. Sadly there are a lot of problems and we could not play together. Not a fan of the newest editions of it so really missing playing like we did back in the day.
Recently my friend got me BO3 and we played that zombies a bunch, even when I was younger I loved playing black ops, world at war and Bo2 with my brother and his friends. Zombies holds some great memories
