im not gonna say if 50 is better or game is better. but for everyone who says 50 wrote documentary, just know dre and eminem pretty much wrote grodt, and taught him how to rap on it.
n*ggas on BX love making speculative rash statements. Eminem & Dre were executive producers on GRODT, therefore giving musical direction (i.e. tell you if a beat sounds crap and should be scrapped or for you to switch up your bars, as well as creative input in songs). The Documentary had about 3 Massacre throwaways which 50 didn't want to use, and ended up on Game's album (I think 2 becoming Game's actual singles).
I don't know why I'm even explaining this, these are well known facts that even Game admitted to, when people said 50 wrote Game's songs it's because they wanted to leverage (i.e. stanning) the fact that some songs were already 50's, all Game had to do was lay his bars and claim the track as his! Hate It Or Love It concept wise was done and dusted already and Game just finished it off! Know the diff please, read up on it if you can't take my word for it
