So, with that said and confirmed, what kind of plot would you all like to see? Keep in mind we are going to work our very best to cut scenario play time back closer to four hours so we may not be able to fit as many sandbox or super roleplay heavy scenarios into a season (we are likely to still have a few).
Also keep in mind this season. We have returned to the exploring and there will likely be 12-15 different locations adventures take place in. Also, contrary to what some keep saying, the season is not all based on tech (aka...don't judge an entire season on the first three scenarios). You will see a variety of different type of adventures. So, what would you like to see?
One of the things to keep in mind is that, if we are going to help cut the time back to a manageable four hour slot, most of the "unique" systems we've put in (mass combat, dog sled race in #16, etc...) are likely going to be done away with.
OR ... Just ignore everything here that you said you can't do and have one double length adventure. Many Game Day events are running two slots back to back. Convention have multiple slots. And, even though it is difficult, you could split one 8-hour adventure (or 9) into two sessions on two different days.
So, sanction a 9-hour, double scenario. Write it in the sandbox style and include one of those items you just mentioned you were going to do away with.
