I would love a game with a timeloop built into the discovery, combat, and storytelling mechanics, a la Deathloop and Prey: Mooncrash, but instead of a first person shooter about murder, make it an isometric heist game that doesn’t hold your hand. You gather clues and tips and tricks through each loop and through exploration, until you build a final plan of attack to end the loop.
Deathloop’s biggest flaw was not playing into the fact that it was, at its core, a puzzle game. The objective markers and notes kind of ruined the climax of the game for me. Absolutely incredible otherwise.
