Games are learned skills: how you engage with a game is something we had to learn. Because accessible, easy to learn games have been lauded as the way to go, we had taugh the player to expect games to tell them what to do: there is less and less agency in games. Players have been transformed from collaborator to observers.
That comes at the expense of their own agency. Games with multipler interlocking systems can present the player with more avenues to solving problems. And by forcing the player to think through the possible plans, re-establish agency in the game world.
