Hmm... played Torment too many times to ever look at it through rose-coloured glasses, and have to agree with Arkan. First time I played it, after being just blown away by the ending, I thought, "Well...what exactly did he do?"
Then I played it again and learned some things I hadn't discovered the first time, and then played it a third and fourth time, and learned a few more things... realized I didn't really want the details of the Nameless One's crimes. Didn't even want his name.
