What are the most valuable games you own?

[Conina]

Probable the Skyward Sword Limited Edition (with golden Wiimote).
And the Bioshock Collector's Edition (with Big Daddy).

Sold the PC-versions of Final Fantasy 7 + 8 for €150 together a few years ago... they didn't run very well on a 64bit-Windows anyway.

And I sold my GC-version of Wind Waker (and Ocaria of Time) a few months ago. Got the 3DS version of OoT instead, Wind Waker HD will follow.
