It IS great. I'm level 13. Don't worry. I won't spoil it. The humor is the same old south park we love and it is consistent throughout. The jokes are also part of the battles. Homless people will ask you for chaaaaaange during battle.
I checked out everything in Cartman's Kingdom before speaking to him for the first time. After a while he commented on that and said "Douchebag already saw everything in my Kingdom. Hardcore player." Something like that.
My best match was 16/0 and I usually do very well. Using DS4 with CQC kontrolfreeks at the "very high" sensitivity setting is fantastic. I have no problems whatsoever and find I do better with the gamepad. Yes, it's true.
