The reason this auction is not going very high is two reasons: you do not have 100% feedback, and although this is a Pokemon game, it received negative reviews overall.
The reviews I read gave it a good rating, 4 out of 5 and 9 out of 10. I was a little worried about your feedback score until I checked. :) I see you really only have 1 negative feedback. I'm watching and will be bidding a bit closer to the end. :)
