I own the entirety of the physical Invisible Sun game, but I wanted to check out the preview material to send to friends curious about the game and unwilling to drop the full price before knowing more about it. There's a ton of content in this preview! The fact that it goes through all the steps to character creation (without the specifics) means players can see how characters are built and know whether that style of game is for them or not. The example cards are a good include as well, and help to give a sense of just how much content this game includes.
The game itself is amazing, and is my favorite RPG I've played in a long time. The way the characters decide on their own priorities, and there's room to explore everything from beating bad guys to starting a bakery. Tons of different playstyles are represented. You'll definitely want a group that's invested, as it requires more decision-making from the players than something like D&D, but that just means you'll all be able to work together to tell an amazing story!
