I was planning to do a 5 class crpg with 3 acts of story, but I think I have to cut it at 3 completed classes, 2 stub classes and only 2 acts (also lots less lore than I originally wanted to write for the story.
Got 4 classes out of 5 (the last is just a stub, actually, and has only early-game nodes, no augmentation/prestiges). But the story was almost entirely undeveloped, and the RPG element was much thinner than I originally planned. Now it is more of a tactical fight/combat game than the CRPG I originally envisioned.
You could also check if the Grit system is still close enough to TTRPG or if it has deviated too much due to the different medium! https://itch.io/jam/grit-system-game-jam-2026/rate/4900160
