Hm... If I was to describe myself as a gamer type... I'd say 'Gamer Scholar' for the fact that I just pile up helpful knowledge real quick and on the fly. Apparently in Halo: Reach, the hunters block their faces with shields while their gun charges, and they drop the shield only when they're about to fire. My brother didn't notice that you can in fact lose the hunter that is trying to shoot you via hiding behind something, or jumping over them once I tried it out a couple of times.
My brother would be a Game Soldier, since if he can't play FPS he won't play the game itself, some sports aside. Nonetheless, he's a pretty good gamer all-around when I drag him into one, though he hates playing the mario games, ever since Super Mario Sunshine, where the difficulty curve is as hard hitting and sudden as Monster Hunter: G2 Unite with the effing Kezu.
