I used to be amazing at FPS games, especially in multiplayer, though it's been a few years since I've played them frequently and my skills have diminished.
When it comes to Strategy games I'm incredibly slow and methodical, in games like Command & Conquer I tend to go somewhere between a Turtle and Steamroller playstyle and wont finish a game quickly.
RPG's are an odd one for me, because I enjoy them a lot but I play every one differently and sometimes it just doesn't work for me, like in Fallout I play with as realistic settings as I can, every single hostile encounter is almost certain death yet I only die real early with new characters on the way to Nipton. But with most other RPG's I'm a careless marauder, smasning my way through everything and taking things without a thought of caution
