Some folks over on the GameFAQs forums started up Operation Decode to try to get this game localized outside of Japan. Since Digimon is a spin-off of Tamagotchi, I figured there'd be a lot of Digimon fans here. The petition currently need 8,723 more signatures before Namco Bandai will look at it.
I signed it several months ago because this game is supposedly like a revamped Digimon World 1, where you actually care for your Digimon similarly to the v-pets. I wish more Digimon games followed this formula because that's what the franchise was originally all about.
If you'd like to see this game localized, please sign the petition in the link below.
