I have taken Poison's snippet "Mini Fantasy Game" and corrected and added some things. I think this will be much easier on the eye.

What I did: I created more weapons for the final scenario and I corrected spelling.

This was a lot of code so it took me a couple of hours to do this all by hand! Basically this is just a cleaner version of it with some additional turnouts.

I know people wanted the spelling corrections done, so I did them.
