Wow, lots of responses to this thread
I'll try to summarize my responses.
1. Okay, I did attempt to 'fudge' the actions of the 1/2 Dragon Ogre in my example... he offered the last standing PC a chance to surrender, which was rebuffed. C'est la vie.
2. I'm not a big fan of NPC's saving the team's bacon, such as Deus Ex Machina, some powerful NPC resurrecting anyone, etc.
3. So far I think the best idea is to just let it happen if it does, allow for some time to reflect (Calmly!) and then try again with different characters. It's tough closing a chapter of your story when PC's die, but in my games, that does happen occasionally.
I think it might be a good idea to find a way to link the 'next' party to the 'previous' party in some way. "You killed my brother!" and all that
4. I'm committed to open rolling as my personal gaming style. I always use it when I DM and it's also the one I prefer to participate in as a player.
What I was hoping to find was some scenario suggestions in which a party could plausibly continue after a TPK. I enjoyed the response which described the party returning as undead... that's interesting!
The backup party is also a good idea... I might try that next time.
Stalkingblue's strategy of Ice Cream and friendship seems like the best recovery method, before working up a new party that is
I'll have to try and get ahold of Carpe DM and see what his "special plan" consists of... and share it here, if there's any interest?
