So I have an extra copy of Lost Odyssey, UK version, untouched, untamed and fully sealed.

Some are selling on eBay for up to 80 $ !!!

Should it gain value with time ? I have no expertise in this type of fetish and also the fact it is on a western console might be tricky...

Keep it. See how things look in 5 Years.

Keep it, then sell it in the next three years or so. If the Xbox One gets backward compatibility through emulator, your priority is to sell the game before it is offered via digital.

Definitely a gem in the Xbox 360's library and destined to be a classic. Underrated, in my honest opinion. Hang on to it if, for no other reason, MY copy breaks. I'll know where to get it.

I'd say play it from a gaming point but otherwise.... What everyone else is saying!

He has this branded game as an extra copy. He already have/play Lost Odyssey :P

Sleep with it. Then decide in the morning.

From my experience. It's worth keeping around.

Is this game rare or something? My local GameXChange has like 10 copies.

Nah.  I don't think it's rare.  Then again, there's tons of NES games that weren't Rare but I'd love to have a boxed copy of.  Even the mega-popular Gameboy fetches a lot of money if it's still sealed.  Out of pretty much any genre, JRPG's are the ones that seem to rise in value.  That's my experience, at least.
