Pokemon Nuzlocke mode.

It's where you make a file on any pokemon game and you go through the game normally but these are the rules you must follow by playing it.
1. you must catch the first pokemon you meet in each new area.
2. every pokemon you get you must give them a nick name. (even the starters)
3. if a pokemon faints then it is presumed dead and you must release it.
4. if you lose all you party pokemon then if you have pokemon in the PC you have to use them instead. if you only have 3 pokemon and they faint then it is game over and you must restart from the beginning.
it is a rather good challenge and a fun one to but there are a few catches if you meet a pokemon and you accidentally kill it then then next time you go into that patch you must try to catch the same pokemon again, you can not move on to a differn't one.
