Champions Online is the outstanding character creator, practically a game in itself. It's a great part of the game, but there's a downside. It's so versatile, and you can do so much, that you can easily make the perfect Gollum or G.I. Joe clone. That's not as awesome as it sounds, because your character will get downgraded to a plain old shirt-and-jeans-wearing guy sooner or later.
"Why is Cryptic so mean?" you might ask. The latest dev blog explains that that's not the case at all. Noel "Destra' Holmes has quite a bit to say about the ongoing issue of IP violations, but it boils down to this: "The requirement to remove IP Violation characters from Champions is completely based on the fact that having IP Violation characters in our game puts us at a legal risk, and the unfortunate fact of the matter is that we are required to remove them from our game, or the owner of the IP in question can take us to court for stealing their stuff."
The full blog entry is very informative, and well worth a read for any Champions Online fan.
