The Grand Compendium
Last Bible Series Spreadsheets
An early spin-off series with a fantasy setting more in line with what you commonly see in traditional JRPGs. Most of these have gameplay similar to traditional Megami Tensei games, albeit in a more simplified form. The sole exception is Another Bible, which is a tactical RPG like the Majin Tensei games. I've played the first two games, but haven't beaten the second yet.
*Some monster tribes in this game (namely the Sarlam and Knight tribes) do not have data available online. Neither do most boss monsters, it seems.
