No Crystarium Challenge

[Ultima Shadow]

FFX for instance: No Sphere Grid, Summons, Overdrive, or Customization. Actually idk if they've finished it but there it is!

I don't think anyone has ever even seriously attempted that. As far as I know I'm the only person who attempted to put the No Sphere Grid and Initial Equipment/No Customization challenge together, and even just those two turn out to be impossible.

You did make it pretty darn far though - beyond a part that was thought to be impossible. Almost to the very end of the game.

I have yet to even play FFXIII myself, but the Doom-thing (which, from what I've understood, results in a Game Over when the time runs out) sounds like biggest issue.

I suppose a FFXIII challenge would have to require a handicap that doesn't make your offensive capabilities suffer too much, in order to get past some of the Doom-bosses in time.

Edit:

NCU (no crystarium challenge) has been completed in Japan, and it was recently completed with the english version as well.

Here's a link to the gameFAQ's thread and page at the point where the game was actually beaten without using the crystarium:

And here's the youtube vid of him beating the final phase of the final boss:

Good news. (Though I won't watch the videos myself yet, as I haven't even played FFXIII normally). >_>
