Fun challenge?

[Ergroilnin]

Okay while reading through various challenge faqs, I got a feeling that I don't really want to CHALLENGE myself but I came up with a set of rules which in my opinion could nicely enhance the game's difficulty and give each character a role to play while not being overly restrictive in using what the game offers.

The rules:

OSG - I can use all characters but they have to follow their respective parts of the SG according to this picture - http://img692.imageshack.us/img692/8881/ffxssg.gif . However, I won't be unlocking ANY key nodes to reach even the parts of their own grid and due to Kimahri's disadvantageous part of grid, I will also forbid myself from placing the extra stat spheres for all characters except Kimahri's. I hope this isn't too confusing explanation? Basically this means I want to balance the party a little.

NO - No overdrives at all. I thought about letting myself use all but Rikku's OP Mix but meh, why not go all the way.

NENNE - No Escapes, No No Encounter, simply I have to win every battle or die trying!

NBB - No Blitzball since it's possible to get very early overpowered stuff like Dark Matter.

IE - Initial Equipment, I will allow myself to customize abilities on them though.

APR - Aeons Partly Restricted - While I find Aeons really strong, I don't want to restrict myself of them because I really enjoy using them. But I won't be getting any extra Aeons (Yojimbo, Anima, Magus Sisters) and I won't be using any spheres to manually up their stats. For fun though I will allows myself to teach each Aeon two abilities and they have to be unique, meaning I can teach Curaga to Bahamut but then I can't teach Curaga to Valefor etc. This should make each Aeon a little more unique a thus strategic in battle.

So since it's cool to make a really long name for the challenge (as seen with NSGNSNCNONENNENBB), mine "challenge" name would be OSGNONENNENBBIEAPR .

I understand that this is VERY specific set of rules that won't probably appeal to anyone else than me but since I started the thread, I might as well post my idea for the people interested right?

Any comments on these rules?

Also even though I think I will go with what I just made up, I am still very open to your suggestions!
