I always put my real name haha just cost I feel much more absorbed in the story if it's actually me in it, unless the game says not to use your real name cost it has online features or something, in which case I always go with my gaming name Laelia :3
Hmm that's a tough one to pick a best character in that, can't actually remember the names haha, was it Marie or something, the main characters little sister, she's sweet and she must of been through soooo much crap in that weird world before her sister got there. I like that girl with the purple hair too, she was cool. I didn't really dislike any of the characters though, by the time I finished all the different routes I sorta just felt sorry for everyone haha.
