I am in the process of playtesting my RPG system, and I want to put together a scenario for convention play. But almost all my experience as a GM is with long, customized campaigns that are highly responsive to player and character contributions. So a highly constrained, pre-planned scenario with pregenerated characters is a totally new thing for me.
I have a few constraints I think are pretty self-evident and I am already working with these:
- Characters must be pregenerated with some customization optional
- The scenario must be of limited scope - I am currently working with a 4-scene budget:
- 1 introductory scene where the players get to meet the other characters
- 3 "encounter" scenes with puzzles or fights
- The objective must be absolutely clear at all times - there's no time for indecision
Beyond those constraints, what else is there?
Is there a good formula for the construction of convention games?
What are the primary features of convention or demo games?
What must a convention scenario absolutely avoid?
