Ever wanted to play an tabletop RGP, but no one else wants to play right now? Having trouble getting a consistent group together? Well stop being disappointed and play Ironsworn! I was initially doubtful about a solo roleplaing game, but I've quickly realized Ironsworn is just so much more fun that I thought it would be. There's so many mechanics and thematic elements that are geared toward enabling solo/co op play that the game is specifically designed to guide you through the experience. I've honestly found it to be very creatively fulfilling, and I even have a weekly group that I already play with.
Thematically, the game has a very low-fantasy, gritty feel to it. There's kind of a nordic flair to much of the art and design of the game, but it's in no way restrictive to that particular flavor. The game seems easily hackable or reflavored, and several players in the discord community have done just that. There's an actual play of a Western-themed game, and I've learned that one player even went so far as to play a World War II game in Ironsworn. Personally, I love almost everything about the "default" setting that Shawn has put together. The Iron Vows are so thematic and great, swords being rare and special is just unique, etc.
The dice mechanic is such an interesting twist and evolution of the regular Apocalypse World mechanic. I think that Ironsworn's base mechanic could really inspire future RPG writers, specifically those wanting to work with Apocalypse World. The assets provide not only mechanical benefits, but help you to understand your character more. You don't just take Oathbreaker because you want to get through it and add +1 to a stat, you take Oathbreaker because your character literally broke an oath and now that's an essential part of your character. Swearing Iron Vows is not only the thing that drives your actual roleplaying, it's also the way you get experience and advance your character. The design is just overall tight and elegant.
On top of it all, the discord community has been great. Shawn himself is friendly and very active on the discord. I would definitely recommend new players join the discord if they have any questions.
Overall, it's a great game and a great community. If you're a little doubtful about solo roleplaying, I would heavily recommend just giving it a chance (it's free!) before you make any final judgements.
