Congrats on your new 3DS .
I really don't agree with the limited replay numbers on the demos, especially on some very low replays like Teathrythym or KH:3D, never saw any particularly logical reason to it.
I'll post my FC here once I'm able to save my game on DQIX (sadly, you can't go into the HOME menu during a DS game).
Edit - Here's my FC : 3780 - 9209 - 1384
