Hahaha!
I caught this one a few days back, and have to say I had a fine chuckle! After finishing old GTA IV yesterday, I had to come back and have another watch, purely because of that remix of Roman at the end. Class!
The general concept was just amusing, a fin take on the GTA series. Voice acting for Niko and Roman were most amusing also! Especially Roman. :D
Good job. But curse you at the same time, that remix was stuck in my head for 8 hours straight at work. :D Not that I mind though, as it is just brilliant. :D
