Infamous, because it's the only one that could be any decent in my mind(in terms of the likely hood it wouldn't suck), the rest of the choices are pretty bad or don't need a movie because they are already great movies and don't need actors to convey them any better.
I think the original Black Ops Zombies storyline would be an interesting storyline for a film. Finding out about Dr.Richtofen and Dr.Maxis and how they were part of each map, especially the change on moon on who was the controller of the zombies, which partially continued in Black Ops II.
Full CGI Warcraft. I don't even follow the series anymore and stopped playing at 3 but goddamn those cutscenes.
The Darkness directed by David Cronenberg.
Anything by Cronenberg. Long live the new flesh!
Halo Film more than anything else. Not the master chief but side story in the universe. Hell maybe even a origin story for the master chief, when he was kidnapped as a kid then cut up and genetically enhanced. I like the Halo universe ALOT.
District 9 is your alternate reality Halo film. Sadly in this existence we will never get one.
Bioshock Infinite. Directed by Christopher Nolan and starring Jon Hamm as Booker DeWitt, Tara Lynne Barr as Elizabeth, Jude Law and Nicole Kidman as the Lucinde Twins, Jeff Bridges as Cornelius Slate, and Kerry Washington as Daisy Fitzroy.
As i said eariler, I think Bioshock Infinite would have been a better movie than game, but damn, you got that cast pretty damn solid. Shit....hell i even agree with your chosen director.
Voted Deus Ex, but upon thought a Civ movie would be pretty cool. Kinda like the birth of a nation, and all the backstabbing and lies that it takes to get a nation to the top of the world. People love legal thrillers, like Argo, and stuff, why not a movie about a growing civilization?
