Revelations The Demon Slayer/Last Bible bestiary
 

I've been working on this for a while now, it's a combined bestiary for the Gameboy Color Megami Tensei Gaiden: Last Bible (Revelations: The Demon Slayer in North America) RPG and the Japanese Game Gear remake of the same title. It's quite interesting, at least to me, to see the monster sprite evolution/changes between the two versions. If you're not familiar with Megami Tensei, the hook for the series is that you can recruit almost any monster you meet into your party and use them as playable characters.

Nicely done. I've always wanted to get into the MT/SMT series, but I just don't have the time to devote to RPGs these days. I love the mix of mythological/religious monsters in the game.

This particular RPG is relatively short--I played through the Game Gear version is two days, but, granted, I already knew what I was doing from playing the Gameboy Color version. I agree that the sheer amount of time required to play RPGs if off-putting at times.

I'd also recommend DemiKids:Light/Dark for the Gameboy Advance (Shin Megami Tensei: Devil Children Book of Light/Dark).
