EU4 with all DLC...

Fire Emblem Radiant Dawn is my favorite game from my favorite franchise ever. It would have to be going for over $1000 for me to sell it haha

Brigandine Legend of Forsena
Suikoden 2
Lunar 2 PSX
Metroid Prime Trilogy Steelbox sealed
Steambot Chronicles
And around a few hundred more that are still $50.

Cory in the House hurrhurr

but my brother does have XBC and Metroid Prime Trilogy....which I tried both but didn't really like very much unfortunately. Shame.

I have a couple of Xenoblades PAL/US. TLS CE PAL/US PT PAL
Misadventures of Tron Bonne
Skies of Arcadia GCN
One Piece Unlimited Wii

Kirby Return to Dreamland. wii

Vagrant Story

Conker 64

is Gold cart Majoras Mask or first print Oot carts worth anything? My Oot is before they censored the music and blood.I dunno I ended up with a lot of stuff later in demand.
Probably a lot more. I don't really pay attention to what is rare or in high demand in my collection just happen to find out some stuff is when I give it no thought.

id imagine my copy of EVO: search for eden (SNES) is my most valuable game. im sure i could sell it for $800+ on ebay. my copy of mega man x3 is probably worth 500-600 as well. those are my two most valuable.

Metroid Prime Trilogy is probably my only valuable one.

Maybe somewhere along the lines of:

Mega Man X2
Chrono Trigger - SNES cart
Dokapon Kingdom - PS2 and Wii
Fire Emblem: Path of Radiance
Fire Emblem: Radiant Dawn

You guys are killing me. T.T

Panzer Dragoon Saga (UK version, complete in box).
Shining Force III
Suikoden II (the presence of the PSN version seems to have only slightly depreciated the value of physical copies)
Valkyrie Profile (PS1 version)
Xenoblade Chronicles (US Wii version)
Fire Emblem: Path of Radiance (also have Radiant Dawn, but PoR goes for about $30 more).
