I need a challenge so I'll play FFIV Advance again.

[f f freak]

I know this thread is 2 month old but anyway

Play the original version (SNES or chronicles for PS) instead of the kiddie GBA version, much harder than any of those challenges

Or you could try Zeromus without a healer using the GBA version. There's nothing kiddy about that. And you can't do it in the original.
