I'm thinking of attempting a Nuzlocke Challenge on my Sapphire :D
The original two rules apply, of course, but these are my additional rules:
-If I get a white-out, I start over. Period.
-Exceptions to the "Catch the first Pokemon you encounter rule" include shinies (I've never encountered a legit. shiny in any of the 3rd gen. games, but meh) and Pokemon that don't require Poke Balls thrown at them (like, for example, Beldum in Mossdeep and the Wynaut egg in Lavaridge; a better example is being able to receive Hitmon- and Lapras in Saffron in RGBY/FRLG, I guess).
-All Pokemon are nicknamed. 'Course, I do that anyways...
