I've got Pokemon fever

[Koopaul]

No it'd be different. You still capture Pokemon but you use them to survive. Once your Pokemon faint that's it! You are defenseless! There's no Pokemon Centers and the game doesn't "black out" you keep going trying to recapture Pokemon to keep yourself alive. Without Pokemon to defend you you will enter a battle yourself, it will be like Safari Zone style except the Pokemon will attack you!
