Despite its label of "Pokemon for adults", the Shin Megami Tensei series actually pre-dates the GameFreak series and first appeared on the Famicom as a Japanese exclusive in 1987. Throughout its existence, the SMT franchise and its numerous spin-offs have maintained a reputation for being quite difficult. It's one that's well-earned, as these apocalyptic visions of the future have tested the might and will of players for over three decades now.
