Breach: The Archangel Job lets you increase your stats pretty often and pretty easily with the free time segments
Vampire the Masquerade: Night Road and VtM: Out for Blood also let you increase your stats pretty often with experience points (though you have more opportunities in Night Road from what I remember)
The only WiP I can think of that’s directly related to an RPG is this one, where you play as a Psyker in the Warhammer 40k tabletop setting:
If you meant games that feel like they were inspired by RPGs, I’d recommend the Lost Heir series. It feels a lot like a traditional high fantasy RPG.
Edit: forgot about 7th Sea: A Pirates Pact, which is set in the TTRPG setting of the 7th Sea. In my opinion it’s the best pirate related game in the CoG catalogue.
Also Pugmire: Treasure of Dogs is based on the Pugmire TTRPG. I haven’t played it, so I can’t really speak to how good it is, but if you want something RPG related there it is.
