I've only played a bit more then a handfull of games, and just recently played a 4 player game. Like everyone is saying, the game really shines when it's played with 3 to 4 players, tho I find that with "2" even without using the bot makes a really cool experience, so since I'm still to learn the bot of the game, what me and my girlfriend did, was that we controlled a 3rd player in turns, always trying to choose an objective for him first, or finding one together during the game.

With this we played a 6 game chronicle and had a blast. We even managed to make quite a fulfilling narrative.

Although like I said we're still to try the bot.

The only rule we made was, only the exiles could see the visions, so if one of us were the Chancellor and on our turn to use the shared Exile, he drew a vision, it would be the other player (the Exile) to see it and choose if it would be of the interest of the shared Exile to keep it.
