Oh, not again....
Don`t you guys get it, it adds to the intrigue, bad endings make way for new begginings!
I agree, BUT ... give the gamers AT LEAST an ending that NOT destroy the replayability and don't break a hero-dream!
Be serious! Read the increasing numbers of gamers they are disappointed with the end !!
Don't forget about many many hours a gamer follow a story, leveling up his hero to defeat the Damned One's enemies .. and then ... crack ... the gamer's dream breaking into pieces!!

And with a little bit sense/feeling of "fantasy" (I'm sure people who makes a RPG like this HAVE fantasy enough!) they can make a follow-up, a new beginning after each kind of ending!!
I wish to be constructive and say (all of this is just some of my thoughts, not more than that

)
* make a forumpoll or whatever that asks gamers for ideas for an ending of such a game like D II (or maybe an upcoming RPG ...).
* and give also the possibility to make more than 1 ending for/in 1 RPG!
* maybe a "competition" and a funny prize for the most rewarded "ending-idea".
* rated by forumpeople they give their meaning about all given ideas! So not only a selected group of people.
