I am reviving this thread with the intention of doing a sequel to the "Jungle Hike" scenario which has been posted above. This would mean in-silico roleplay. A very short summary of the previous scenario follows:

Six G.I.s (five humans and one ork) survive a helicopter crash in enemy territory. They need to march 60 miles through more or less dense jungle vegetation including hills and mountains to reach the safety of the next American military outpost.

Sequel:
Title: R&R in Saigon
Description: The characters are recovering from their ordeal of walking through enemy lines. So they enjoy sight-seeing in Saigon. Though despite being on vacation they can´t rest too easily as trouble finds them even in such a more or less "safe region".

Note:
I have never done online roleplay before so what do you think is the best approach:

1. Write the ENTIRE story beforehand and make notes where players are to be involved and where they can choose more or less the path to change/affect the plot?

2. Advance the plot on a weekly basis?
