WoW. I love the simplicity.

Eve Online has a very good one. The models are aging these days, but you can sculpt some very unique faces.

Some years ago I played a game with a deep customisation for character creation. Well I was quite impressed, I was used to MMORPG where you had 6 faces to choose from, 6 hair cut and hair colour.
In this game you could customise many details, head size, body size, height, and many cursors for face details.
That game was Perfect World, it was probably around 2008-2009.

I guess now many recent MMORPG do better when it comes to character creation.
