You dont need a verification e-mail as far as i remember, meh the reason you clocke dit so fast was because you played it on easy, not even Regular. . . honistly you can't moan about the length of a game when the mode you play it on is like pusing over garden Gnomes.
Play it on Regular and it lasts about 6 hours, but even thats short but hey dont expect a long ass FPS game because it will get boring quick and then the devs will be forced to use the horrid thing that is CRATES ! and if you go crates in a game it means the developers had no idea what to put in the game.
anyways welcome to the forums and give it a bash on Regular and your be a happyer man
