It took me some 13 hours to finish it, but it felt like 40 hours cause the game is so fundamentally boring. The levels are too big and empty and Hector is a bit slow. Or maybe he just seems slow cause the levels are so large. Anyway, the game moves at a snails pace.
However, the soundtrack is terrific, one of my all-time favorites.
Also, I don't see how anyone could say that CoD has better graphics than LoI?
To each his own, I guess...
