'Watchtower' was such a lovely experience, and exactly what I was looking for in a solo RPG journaling game. I loved the experience of copying out my own map and filling it in as I explored. The random tables were excellent, and I loved all of the created NPCs, both the other watch tower staff and the random visitors you could encounter. This system was nice and flexible -- I extended my character's "contact" when I decided I wanted to keep playing, and I pivoted the story to be more supernatural when I ran into the same weird NPC three times in a row.
Loved this game, and I can't recommend it enough.
