World of Warcraft (and its expansions) have been awarded numerous awards, including Best Game of the Year (multiple times), and Best MMORPG. As far as best game ever, that would probably be hard to say.

World Of Warcraft MMORPG
Yes, its one of the best MMORPG browser-based games.
Monopoly is of course the best.
Blizzard holds the record for largest mmorpg with their game World Of Warcraft.
Well i presume the best RPG game ever ( according to addicts ) is World of War Craft ( a MMORPG ) or Final Fantasy.
