Dragon Quest Monsters
The original two games were exclusively Game Boy Color games and were not backwards compatible to the original Game Boy. The games also used the largest cartridge available for the Game Boy Color game system, which was four megabytes. Enix developer John Lawrence stated that Enix wanted to give players options in "Dragon Quest Monsters 2" where they could play the game as a solo RPG, but created two parts of the game to encourage players to have a social experience of playing together like an enhanced version of the original "Dragon Quest Monsters" or like "Pokemon".
