Is  Red Harlow  & John Marston the same person? they both have the same scars... i think 

Nope. Thats pretty much the only thing they have in common.

hmm then shouldn't they change the name from red dead to something els... 

" hmm then shouldn't they change the name from red dead to something els...  "

so what if its not called red dead revolver 2? 
its not like the characters name really changes the game... its the character himself that changes it

i know its not called red dead revolver 2 but the main characters name is john marston not RED harlow
