Yu-Gi-Oh! - Forbidden Memories

Yu-Gi-Oh! Forbidden Memories casts you as Prince Atem in ancient Egypt, where duels decide the fate of a kingdom. Unusually for the series, it uses an early rule set in which cards can be fused freely, and discovering which combinations produce powerful monsters is most of the game. It is famously demanding: opponents draw strong cards early, and building a viable deck takes patience and a great deal of repetition. That difficulty is exactly why it retains such a devoted following among fans of the card game.
