This details a Final Fantasy 6 Low Level Game's progression as completed by me. The average level is 7.33 at the end (which is the lowest possible without using a cheating device or abusing a bug). There are a few rules I used:
1) Any fight that can be avoided that gives Exp. must be avoided.
2) No bugs are allowed to be used (Psycho Cyan's killing bug, sketch bug, invisible enemy bugs)
3) No *purchased* rods may be thrown. Any rods you seen thrown are from treasure chests.

Finally, you'll notice I tend not to use Strago as I wanted to make things a little more difficult on myself and Strago's step mine is a little overpowered, although if you do ever play an LLG he is very much a strong party member.

I hope you enjoy all the boss battles :)
The later ones tend to have the best quality (as I taught myself how to record and compress videos as I went along)

My second Low Level Game to be uploaded to youtube. This is done with Super Mario RPG: Legends of the 7 Stars.

The only rule for this Low Level Game is not to gain unnecessary experience (to keep your characters at the minimum level possible).

The ending levels are as follows:
Mario (Level 3)
Mallow (Level 4)
Geno (Level 5)
Boswer (Level 8)
Princess Peach (Level 9)

There are no armor, weapon and item limitations (unlike FF6 where you're not allowed to throw rods).

Again, no boss battles' fights use save states in order to defeat them, albeit I do save state to assure I lose the "Chance" game (so I don't have to repeat boss battles).
So all you see is unedited battle possible on the catridge version!

This details the boss fights from Xenosaga Ep. 1. As far as I'm concerned, there isn't one completed to date, and there certainly aren't any guides out there to the best of my knowledge.

This will be delving into unknown territory, for sure.

Update: Completed 5/2/09
Perhaps I should write a guide, seeing as there aren't any available?
