It's a difficult thing to handle such a chaotic scenario and a bunch of rowdy players looking to mess around with the game as much as possible, but CosmicalRabbit did a wondrous job running us through Mothership, teaching the game and managing all the mechanics nicely!

This is easily one of the most versatile narrative systems ever made, with clear and simple mechanics that might be overwhelming if you're coming from more mechanically-focused systems, but with plenty of materials including the Action Grimoire to support that transition, and a ton of flavor oozing from every single page of content, Otherscape is one of those systems that changes your perspective on how to run a more cinematic experience in any other RPG you might play! The only downside I can think of is that for players, you do need the buy-in of building up a collaborative story and that the system itself leans hard in sandbox play, giving extra power to the players in deciding what's happening next. This might be a problem during the transition between other systems and the Mist Engine, even between other narrative games like PbtA or FitD, but it's a learning curve that is well worth it to approach and surpass to enjoy the beauty of the updated systems and all the amazing flavor included for guiding your personal stories!
