TheGuitarGuy - The game is divided into levels, but there´s no loading times between them, only FMV´s sometimes. It´s like your playing a level, then you get to another part of the map. The level´s title appears on the middle of the screen, but there´s no loading, no stopping. It´s awesome! The game only stops on the cut-scenes.
And the average time to finish the game is 8/10 hours, I curently have 6:30 hours on it, but I´ll probably need more than 10 hours to finish it, since I keep fooling around testing new combos or searching for hidden boxes all the time.
McLaren F1GTR - Hydra is the first boss of the game if I´m not mistaken. It´s really cool to fight with her, specially being the first boss you deal with. It´s not difficult to beat her, but it´s not that easy too, it gives you a good impression of what´s to come.
And I don´t consider GoW as an Action RPG. The only RPG similarity the game has are the weapon´s upgrade. And that´s pretty simple to get too.
The controls are easy to learn. You can just smash away the whole game and you´ll be fine, but you can also try to learn and master the different combos. And there´s a LOT of different moves, which keeps the game always fresh.
By the way, the control scheme of this game is one of the best I have seen. It´s very fluid to play it, and the dodging move on the right analog was an awesome idea!
. But it's the best I could explain my question.
