We know that they made a song together in 2005 for The Documentary but then all that beef with 50 happened and I heard he wasn't even talking with Dre for a determined period of time after he left Aftermath because Dre had to make something like a choice (so did Em I think) between support him and 50 and he choosed 50 because he was on fire at that time (He had just released The Massacre).
Then Game made two albums without any support by the Aftermath family and for the R.E.D. Album he finally started to work with Dre again.
After the comments Game made on Recovery and Em ( http://www.youtube.com/watch?v=KbHPpdPhlic , makes me laugh everytime

So the relationship between Game and Em is either good or not?
