Some of them wouldn't make a bad movie provided the original writer and developer closely works with the makers of the flim...
The following games I do think would make a decent movie tbh...
Metal Gear Solid (2009)
Splinter Cell (2010)
World of Warcraft (2011)
Although, not a fan of WOW but I enjoy Blizzard's cinematics...They are short of amazing
...just look at Starcraft. That would make a good movie tbh!
Prince of Persia would have been good if it had Michael Bay directing it. But now its some w*nker who directed Harry potter its going to bad!
