Mountaintop Isolation is the first W&A game I've played, and I couldn't be more pleased about my introduction. The rules are simple and clearly presented, allowing you to jump into play after minimal setup (you have a deck of cards, a tumbling block tower or tokens, a d6, and something to record entries with? Congratulations, you're ready to play!).
The overarching themes of the game are present throughout the prompts, allowing you to build a narrative that is both fraught and terrible - and that promises to get worse as time goes on. One question my character kept coming back to was "where are my friends, and why did they invite me". That answer shifted slightly over time, and not for the better.
I played this game about three weeks ago and it has been on my mind ever since! Definitely suggest giving it a go, and if you'd like a more detailed review you can check mine out [here].
