The Dark Eye: Book of Heroes, which is based on a TT RPG system, is going RTwP. Not much of a TB trend if at all. Seems like it's primarily the D&D-based games (Realms Beyond, Solasta, BG3) that are going TB. And it is precisely because those three games are D&D-related that I will even consider playing them (backed the first two; am open to BG3). Dark Envoy as a TB game gives me no incentive to bother with it (whereas I did play and enjoy Tower of Time).
