Part 1: Intro
The first game was also one of the very first RPGs I played at a young age.
As an aside, the SNES version used different box art from the others. I bet you'll never guess what kind of monster the final boss is!

The plot is very basic.

I'm kind of amused by the cleric praying rather than getting any type of equipment.
That's right, we're starting with a sewer level, baby!
Uh oh, looks like the heroes are about to be the victims of some major orb shit. This line is excluded from the Sega CD version.
The only way out is through now.
