If you're tired of such moves, maybe a slower-paced FPS would suit you better, such as Rainbow Six Vegas. The game has much less to do with keyboard skills and more to do with tactics. Also, with a game engine inspired highly by the Quake series, I'm surprised you haven't figured out that strafe-running, bunny hopping and grenade/rifle jumping is somewhere in the top of game-play considerations.
