The Game -- I'm Rich and I'm Hung

EXCLUSIVE

The Game has a very clear picture of who he is ... an extremely rich, extremely hung rapper.

Game was leaving the epic Casamigos party Friday night when our photog asked about the Instagram pic he posted packing major heat.  

Game insists ... he didn't do it to hawk his new album.
