Actually, I think that they should have won more awards for their work, and maybe Michael Hollick should get some recognition for his voice work as Niko Bellic.
Grand Theft Auto is still the best video game series around that has been improving with every subsequent release, as well as creating a unique feel and atmosphere for every title (whether big or small), and that's a really great achievement. Some games still follow the same style every game with better graphics, more features and longer storylines (Halo 3, MGS4, etc.).
And, to add, although MGS4 was great, but every MGS game is pretty much identical in feel. Developers should learn from R*, particularly R* Games, R* North and R* San Diego.
