Halo 3 is so fun to play!
I understand that Halo 3 is a first person shooter. 
I love playing first person shooters. Do you know when the game released?
Halo 3 was released in 2007. 
How much revenue did the game gross?
I have no idea.  I do know that Microsoft spent 40 million marketing that game. 
Wow, that's a lot! No wonder it's so popular. What makes it different from the previous titles?
The story arc is a continuation of the two previous games so I'd imagine it is the same old same old.
