So about two years ago, I picked up a used copy of the Metroid Prime Trilogy collector's edition for $20. Pretty good deal. Now, a local game store has a copy of a collector's edition of Tales of Vesperia, which they're selling for $175. I am wondering if it would be a fair trade for my Metroid for their Tales, if I'd have to pay more, or if I'd even get some extra money. Help and opinions would be greatly appreciated.
