Milk it. (Tip: Turn on some musical games while you do it.)
Have a blender and the ingredients reserved. Add the famous MMO to the blender, add the 3 incoming call of duty games, add starcraft 2. Add some DLCs and two expansion packs. Let it rest for two years.
Now, add diablo 3, add next bungie IP game, add maps/mods/songs via store, add lots of DLCs and sugar. Add 600ml of pure marketing water for profit, and blend it. (more like $600M, huh?).
