Okay guys,

for the time being I am just brainstorming since I am and for some time will be playing P4G but I am thinking about what could be an actually fun, enjoyable challenge?

I've played and finished the game about 6 times before, two times with Penance and one challenge run - NSGNSNCNONENNENBB which I actually posted here somewhere few months ago. This one was really nice to play, but with it being so restrictive I actually had to use walkthrough alot for required items that cannot be missed, which took a lot of fun outta it,

So now I am trying to come up with what could be a really fun challenge that doesn't require a walkthrough (like NSGNSNCNONENNENBB) and actually is fun for the whole game. First I thought about doing Rikku Only NSG and got very excited about it, but when I was thinking about strategies through the game bosses, I realized that after Calm Lands it's pretty much 4 of 9 and some multihitting items to kill everything so it lost it's charm.

Any ideas?
