The legacy of Pokémon spreads beyond the scope of collecting and squaring off against other monsters. You can play pinball, the trading card game, puzzle challenges, dungeon adventures, and more. You name it, it's probably been done. Pokémon doesn't encompass only monster battles, and that makes it easier to branch out to other titles on handhelds. There are other options if the main games don't seem to work out for you, so people can still purchase the systems they desire.
