Idk. I’m going in the opposite direction. Shadowdark has brought such a fresh enjoyment to the game for me, taking everything I like as a DM from 5e, cutting out all the cruft and bullshit, and condensing it all into a sweet ichor-like-syrup. Player characters can actually go down, I don’t have books worth of subclasses to know (all of which have long since blended together), classes are distinctive and specialized; I can’t recommend it strongly enough.
