if it's just a lil assistance with a recommendation that's fine. remember even jay z did that in the fade to black documentary when kanye told him how he should start off that last verse on "lucifer".
but to be considered one of the greats lyrically in the game, to be in a sprite campaign with true legends, etc...and then have this blatant copying over exposition? this is ROUGH to just let slide.
kanye contributed a ton to the game through producing and such before he became a rapper. so, regardless, i think he should be viewed in that same lens that dr. dre is viewed in like funk flex mentioned. nobody thinks of or expects kanye to be a great straight rapper/lyricist...IMO.
