Are you bored of replaying through the same games over and over again?
Want a stupid ridiculously hard challenge?
Want emotional trauma?
Nuzlocke is for you!
In order to play this, just take any Pokemon game and start a new file. There are certain rules you have to adhere by though.
1. Catch the first Pokemon you encounter in each route/cave/whatever and nothing else. If you fail to catch it, too bad, continue onwards.
2. If you Pokemon faints, consider it dead and release it.
These are the original rules made up by this guy who created the challenge. He now makes comics detailing his misadventures with his own Nuzlocke runs.
