WoW can be either rpg based or pvp (player vs player) or both. u do quests and "instances" with with groups. kinda like diablo 2 but way better imo. u can also kill each other by dueling. it's fun. try it out
Guild Wars. Counterstrike source. Have not tried COD 2 online yet still working on the missions. NOODLE If you liked Diablo 2 Guild wars is awesome and there is no monthly fee like World of Warcraft.
i only play original WC3, havent gotten frozen thrown. So if the rest of MR is like that we should start playing some games. Always need a friendly group to practice my melee games. I mostly play Custom maps- TD's r my fav.
