what is the best ftp mmorpg?

What game is the true best free mmorpg, i heard it was this one, but i tryed Guild wars and its not to good.

i want one where it is 1 big instance like WOW and has a good amount of players, and good graphics.also, customation is a big thing(class/ race)

thanks in advance

Diablo 2: LoD still has a huge population of players in the East and West Realms, over 50,000 players I think, Its not as much as WoW's 9 million, but theres always people online in d2, I played it for 5 years, and It was good times, great RPG elements, great MMORPG elements, its just a great MMORPG !-Origin-

It's not MMORPG...

You are expecting a little too much from a free game. All F2P MMO's are horrible. Except Anarchy Online, but AO is P2P too.

A free mmorpg , im also waiting for Zu online, Seal Online and Project Wiki. I have seen some youtube videos related about these 3 games and i like it alot, specially project wiki the graphics, the characters, the speech seems like zelda!

A payed mmorpg, absoluctly Wow , (Don't know about WarHammer if its to p2p or f2p), Age of conan, Ragnarok 2 since everyone is saying it has better graphics, commands and stuff from wow...
