That's a good point. I never thought about it that way.
Actually, it would be more if you go 3D and get popcorn, drinks, candy etc. Oh, and dont forget parking.
BTW, I read in another thread that you needed to have a copy of the disk? Does this mean I cant play the DLC if I have the digital version?
You can play the DLC as long as you own the game whether its digital or retail. Just make sure the regions match up.
