I agree with all on the list except Halo and Left 4 dead.
A movie about a group of friends escaping from a city overrun by zombies = awesome
Also, a Halo movie would be a FUCKING MASTERPIECE! That game is destined to be a blockbuster movie of epic proportions.
I have to agree on GTA though... It would be woeful
My prediction threads:
Wii U will sell under 40m units (made on 14th September 2012)
PS Vita will sell under 20m units (made on 30th September 2012)
Wii U will sell under 7m in 2013 - I was right
