I'm working on a solo Journaling game called Wail. Its sort of a spiritual successor to my Last RPG Jam entry from last year The Singing Sands.
No stats or classes, you define a characters history (or roll one) which influences their starting items or Keywords/Skills. Then during encounters or actions your Items/Equipment and Keywords positively affect your pool of d6s, while Injuries or negative Keywords reduce or hinder your pool. While playing you build a hex map, gather allies to your base which can assist you and explore the locations. Really happy with the map making at the moment and now I'm onto defining the tables for exploration and encounters.
