Failing Is Fun
I was in a game ages ago where the Paladino routinely had some kind of critical botch, usually followed immediately by a spectacular roll to recover...things like getting ambushed while on horseback, the horse rears, he botches a Dex roll and falls out of the saddle, then rolls a natural 20 to land and comes down squarely on both feet, having just, apparently, done a backwards somersault dismount in full plate and now on the ground where both he and his horse can attack the ambushers...
I was also in a Star Wars game with a mercenary who couldn't hit a starship from five feet away with a blaster...until she got wounded, and once she took a die penalty, her rolls went golden and she could shoot the range-finder off Boba Fett's helmet from 200 meters. Also had an aspiring Jedi whose wild die routinely betrayed her when she was trying to resist using the Dark Side of the Force...but once she gave in, she would get wild-die bonuses on just about every roll (I think her record was rolling 40 on her wild-die, alone, plus the rest of her dice roll, when trying to telekinetically crash Darth Vader on a speeder-bike...)
