Sentinel Comics RPG by Greater than Games and Critical Hits studios would be incredible on demiplane. Because the character creation for the game is so robust but formulaic, a well-designed character builder like the one on Demiplane would be an easy fit for the game. It’s also a game that’s in it’s earlier stages of releases, meaning that putting the content on to Demiplane wouldn’t be overly time consuming.
I’d love to see this game reach a wider audience, as it’s quite simply one of my favorite Superhero RPG game systems.
