The only self-imposed challenge I think I've ever done was playing Pokémon. It's not the Nuzlocke Challenge, just something I made up for myself to make the games a bit more interesting. Still only two rules, though: knocking out wild pokemon is not allowed (so no grinding; experience can only be gained against trainers), and I cannot use more pokemon in a battle than my opponent.
It's a simple way to really enforce the strategy aspect of the games and prevent myself from being lazy and using my starter in every fight. I do usually have to drop my rules and grind like a mother when I get to the Elite 4 though, haha.
