Depending on how you define flop, I don't know if I have played any that flopped undeservedly. If you just mean weak, BioShock: Infinite definitely deserved far more success than it got.
Back when in its early years I would have said Mount&Blade, which did terribly enough to be PENNY clearenced out of GameStop. But the game and franchise have grown consistently over time on PC and is now considered a noteworthy success and has spawned an enhanced pseudo-sequel (Warband), a full sequel (With Fire and Sword), inspired a sister IP (War of the Roses), and now another sequel (Mount&Blade II: Bannerlord). So yeah, once a flop now a hit.
