Playing Final Fantasy VI again has kind of made me want to replay FFVII as well. But whereas twinking out in FFVI makes the game more fun because you can build highly varied characters through differences in equipment, relics, and esper stat boosts, taking full advantage of FFVII's materia system ends up making the game pretty dull because every character ends up basically the same. That's why I need to come up with some extra rules to spice things up.

So far, I've got:

• No Knights of the Round
• No more than one summon materia equipped in the party at one time
• No multiples of any materia equipped in the party at one time

Can anyone come up with other good restrictions? Note that I'm not looking for wide-sweeping bans on stuff like a command materia only challenge because that sort of thing only makes the game more repetitive. I want ideas that help balance out the broken materia system and encourage character diversity.

If I do end up replaying FFVII, it won't be soon since I don't want to jump into another really long game right after FFVI, but I figured I'd toss this out here for now. And I guess this is also to see if anyone would be interested in watching a stream of the game.
