One thing I find very annoying about MMOs is that they require you to have a unique name for your character. You spend a while making your character, getting excited, then you get to the naming part, and spend the next hour trying to think of a good name that's not taken.
Some games have corrected this, such as Neverwinter and, while not an MMO, starcraft 2, but I think all MMOs should remove this restriction.
I would like to see other peoples thoughts on this. Is it annoying? Is it really not that big of a deal?
If possible, the creation a list of MMOs with their naming rules would be great.
