Before I knew exactly what was going on with the Tenpenny Tower quest, I killed Mr. Tenpenny. I want to complete the quest the good way, and I have found out I can't do that with Tenpenny dead (even though when I killed him I got + karma -.-). I convinced all the people to let Ghouls live in the tower before I used the console to resurrect him, and now he doesn't have anything to say about it. Is there a console command to get the right quest state like there is in Morrowind and Oblivion? Thanks in advance.

If Tenpenny's body is still there; open the command prompt, click Tenpenny and type 'resurrect'.

There is no good way to complete that quest. If you manage to get the Ghouls into the building, they end up murdering all the other residents anyway.

I've only played through the game twice now, and I am working on finishing quests in a different way than the last time...and just found that out the other day. I was pretty mad at our friend Roy so I opened up a can of deadly MILF justice.

I don't even bother with that quest anymore, I just ignore it. I don't want to be an evil bastard and simply kill the Ghouls off, yet I don't want to lose all those extra merchants either. Gustavo especially has some good stuff for sale. So while I don't care for the people who live there, aside from Daring Dashwood, the only option is not to get involved.
