In the world of GIJoe, where the heroes are treated well and are well loved by all, Rambo wouldn't have made much sense unless they did an alternate retelling of it, he also wouldn't have looked terribly unique versus the other joes.
Where as Rocky is more optimistic and kid friendly while showing people the importance of digging your heels in and not giving up. If you look at the context it makes a lot more sense.
