The Bandai WonderSwan was a competitor to the Game Boy (interestingly, both were created by the same guy) that never made it outside of Japan, and so it doesn't have many games in English. Much of its titles are anime-licensed and RPGs, but it also has a decent number of (import-friendly) fighters, platformers, and action games. * Classic: 30–40 hours * Color: 20 hours * Crystal: 12 hours There are also AC adapter and rechargeable battery pack accessories for those who'd prefer less battery expenditure.
