I am (or was) rather good at RTSes. Back until around 2001, I managed to maintain a pretty rad BattleNET ladder score on Starcraft. Now I am merely reasonably good at them. Except for Age of Empires 3, which.. didn't sit with me for some reason.
I am quite decent all-round at FPSes, but hate most 3PS games, especially the retardedly oblong-cam 'over the shoulder' ones like Dead Space, which was, frankly, extremely disorienting.
I am average at fighting games, but anyone mashing buttons fast enough is average at fighting games, so I suppose by general gamer standards I suck at them. However some of them I suck more at than others, like Soul Calibur 3 and 4.
I can't make any excuses for my performance in Dragon Age though. When I first posted about the game I complained that the gameplay and level-up mechanics are unintuitive and impenetrable, and I completely missed out on any proper healers during my 3 day stint, but I have to concede after some distinguished thought that it is me who sucked and not the game.
And I am horrible. Horrible. At Super Smash Bros. But that may have to do with my lack of motivation to play the game well.
