WoW, which you probably already heard of, is awesome. $15 a month is worth it. 10 class, warlock, druid, warrior, priest, paladin, death knight, rogue, shaman, mage, and hunter. At level 10, each class have a choice of choosing between 3 talent trees, although, you can hybrid.
There are two factions you can choose between, which have different races, Alliance and Horde. They are enemies, and if your on a PvP server, the opposing faction will be hostile when in a neutral area. There are 10 races, human, dwarf, gnome, nightelf, and draenai are part of the Alliance. Orc, Troll, Tauren, Undead, and Blood Elves are part of the Horde.
PvP in this game is really great, as there are so many skills, weapons, armors, talents, etc.
