From the introduction: Solo roleplaying constitutes a particular niche in the gaming world, many games of this type have come out in recent years. To play a solo RPG you need a solo rule system and a tabletop RPG of your choice. After playing with many different systems I've found that I prefer very simple rules, this helps me focus on the story and characters, and I do not need to print a lot of material or bring with me too many files. Recently I wondered what could be the minimum necessary for a solo role play... flip a coin and write a story? I said it is ridiculous, too casual and largely ineffective, the challenges will be too trivial and then how I would find the inspiration to continue an adventure? Meanwhile, however, I kept thinking it would have been interesting to have such a simple game to learn it by heart and play with it forever, a game that did not require any particular type of dice or deck of cards or many tables. If you, like me, want a game that is extremely simple but that includes both the Solo Rules and the RPG, an auxiliary system to play when you do not have time or space to use more conventional RPGs, here it is. The name is BIVIUS Solo RPG, it has 8 rules. I could not do anything simpler than this that works for me and I find it surprisingly fun. If you have some solo role-playing experience maybe it is worth a try.
