9. What is a good RPG to play for about 10 sessions?
If you know you’re planning for a mini-series rather than a campaign that goes on indefinitely, it helps to have some scaffolding to help pace the overarching story.
One type of scaffolding is a campaign like that provided in Night Witches where the duty stations are outline along a timeline but your airwomen’s adventures at each point, and how fast you move from one station to another, depends entirely on your group’s choices. Then there is a game like Blowback that provides tools for escalation of the plot with certain preferential paths but still leaves you free to make the choices that will shape the overarching story.
A more structured type of scaffolding might be the Plot Point Campaigns included in many Savage Worlds games such as Low Life, Mars, Necessary Evil, Sundered Skies, Slipstream, Thrilling Tales, etc.—although their length varies and you may have to pick only a few of their many episodes.
