This just wouldn't make sense. As Lester said "There was a guy in Liberty City making moves, nah, he went quiet" and as Packie McReary said "I don't know what got over Niko". I can't really see him moving to Los Santos, I couldn't even take Johnny Klebitz serious as he moved to Los Santos for some reason, clearly insulting his intelligence. If Niko moved to North Yankton (Canada), the game would seriously become ridiculous.
North Yankton is based on North Dakota, not a place in Canada. I agree with you on your points though.
are people really buying all this about the so called "north yankton DLC"? it seems very unlikely given the fact that ONE guy has found this code and refuses to share it immediately but insists that he'll make a .rar file "soon enough". not to flame him or anyone else but the dialogues he's posted seem very incoherent and even too basic for them to have been written by Rockstar. I could be wrong though but no one can blame me or others for remaining sceptical...
on a related note i find it quite interesting that this guy has made a vice city mod with niko as the protagonist and here on these forums he is posting ambiguous codes implying that niko will return as a main character, even though rockstar seem to have repeateadly hinted (both throughout the game and through official statements) that niko will not be returning. im sorry but it all feels a little sheisty.
