I don't get why so many people are getting mad just because we're getting only a few new scenes, the entire game is getting overhauled which means new dialogues, not to mention new gameplay and busts. That means a whole game's worth of new content!
Be happy he's back, be happy he wanted to finish the game, and stop finding reasons to complain - I waited patiently for six months give or take all on a hunch he was not only going to come back but might even be working on Urban Demons in secret. It paid off, Nergal came back, we got a guarantee he will finish the game or hand it over to Glassfish to finish it.
Patience is a virtue. If it takes a while, its going to be worth it in the end.
