Original Digimon Monsters Digimon World

From the introduction: This place seems familiar doesn’t it Jumper? A digital world filled with strange creatures, inextricably linked to a world so similar to the one you used to call home. Where the bonds of friendship and virtues of your heart can shake the heavens themselves, and the weight of destiny falls upon long-since prophesied children destined to bring about a new age of peace as they fight against ancient evils. An idyllic place for adventure, no? Or at least it used to be.
