I've been playing it mostly as a solo game, and it's been great, it's complex enough and got enough randomness to keep it interesting; the die rolling so you never quite know how a mission might go, randomized scenarios, random card availability.
I got this for the tear dice to make the game a bit less brutal. After a few plays and watching some videos I don’t need them anymore but I do recommend them! The dice tray is awesome and I use it always!
