Lineage 2 by far. Been playing it for about 5 years, also ran my own server for a few years. If i had to guess i would say i have 10k + hours into that game.
i love uphillrush games. i am thinking to shoot the videos of my performance and publish to youtube but i have not won all steps yet.
For the past year I've been playing a lot of Dawn of War 2, I played some Modern Warfare 2 but not nearly as much. Looking forward to Call of Duty Black Ops which is coming out very soon.
