What makes a character a good character?
The title pretty much says it all. (Apologies, Digi, if this is a repeat thread.)
What, to you, makes a character good? What makes you a fan of particular characters? If you have any example characters then that would be good too.
Is it their origins? Is it their tragedies? Is it that they're easy to relate to? Their character design even? Or is it simply that they beat this person or did that thing? (A lot of the time to the outside observer this last reason does seem like the reason some characters garner fans.)
On the flip side, what do you think makes for a bad character?
