I bought summon night 2 on ebay a few days ago and am nearly certain this is fake for a few reasons. Mainly I was playing through the story and about an hour in I was only receiving 1 exp per monster I killed when I watched a walkthrough I saw that they were receiving 30+ exp for the same mobs so yeah pretty obvious red flag. I opened the cart and saw a circuit board I've never seen before. First off it had no battery (will post pictures) and you can see a poor soldering job on the chip with I would assume is the game itself. Anyways I'll just post these pictures and hear what you guys have to say about it. http://imgur.com/a/sAqdi
