Both names are not "correct or acceptable" when one name is used as a default; "Chaotix" is the name used for all regions, including any English-speaking one, no exceptions. The only reason so many sources use "Knuckles' Chaotix" is because they don't go by the game itself, which is simply wrong by any metric, and it's one of the many things that calls their title-fact-checking into question (I'd start a list, but WP:VG has made it very clear that they refuse to deal with the situation no matter how much proof I have). Again, we write articles on the games themselves before we write about the packaging material. 

 You want this to be about Sonic Colours? So be it. You no longer have your nonexistent ENGVAR argument, so what's your game, Sergecross? How am I supposed to assume good faith when you continue to lie and lie and lie to my face? How am I supposed to assume that these many editors aren't simply banding with you, Mr. Almighty Admin, when I never see these people elsewhere and when they say things that would suggest they're actively ignoring what I say? Why would I assume a particular situation when every single sign tells me that things are the complete opposite? I am simply unable to use Wikipedia in any wayto read, to edit, to discussbecause of you. Why are you treating me this way? What do you want me to do?
