We are seeing TTRPGs modernize. Although someone said that OSR is looking backwards, part of the OSR movement has involved, for example, examining these older TTRPGs as "games" with intentional design and realizing that B/X had a fairly solid game design. This has also led to things like NuSR and OSR-inspired games, such as the Odd-like games (e.g., Into the Odd, Mausritter, Cairn, etc.) and even Forbidden Lands. This process has involved a greater intentionality of design around things like exploration, hex crawls, the resource survival mini-game, and random encounters.
Much like with Odd-like games, we are seeing other games like the recent MCDM RPG question the need for attack rolls or if characters should just automatically deal damage.
This is not even including other more narrative-games, such as the PbtA or FitD family of games.
