Kyūyaku Megami Tensei: Megami Tensei I - II (旧約・女神転生I-II; lit. Old Testament Goddess Reincarnation: Goddess Reincarnation I - II) consists of Megami Tensei and Megami Tensei II being updated and ported to the Super Famicom. It was released only in Japan in 1995 after Shin Megami Tensei: if... and on the heels of Majin Tensei II: Spiral Nemesis. However Atlus did not take too many liberties with the original gameplay. A few portions of the dungeons of the first game were redone, along with a new save game and teleportation terminal feature which previously did not exist. The graphics and music were enhanced to match the capabilities of the Super Famicom.
- Japan: March 31, 1995
Kyūyaku contains a number of "easter egg" scenarios not present in the original titles. Typically many of these involve actions taken in the first game (Megami Tensei I) effecting possible side adventures and rewards in the second game (Megami Tensei II). Though possible to play the games in reverse order, you will miss out on these exclusive features. In the Megami Tensei II portion of Kyūyaku four new special Majin make an appearance, however their stats are each identical to another devil, so that they offer no actual advantage to the player. The Majin include Artemis, Leto, Oberon, and Zeus, all in an original visual style. Kerberos is also rendered in an original and striking fashion. However most devils appear similar to their Megami Tensei II 8-bit counterparts.
