Many MMORPG's are examples of a general selection, becomeing unique through many choices.
Guild Wars, World Of Warcraft, Runesape, Shaya, and many others.
You get a general Race Selection, then you have Class Selection, then you have specific abilities. The combinitons could be endless.
(Hint... Hint... Designers) What would be nice is MANY specific abilities to choose from in a CAMPAIGN mode. (I hope the current campaign mode is NOT just 5 or 6 short levels. But if they are then I'll just have to play multiplayer.)
