I know what you mean. I finally caved and bought it new at gamestop for $30 last week. It's probably not getting any cheaper and that's not really a bad price. I followed pricing searches for a few weeks but not many places are selling it and the price is probably just going to go up. Before this I can't remember the last time I bought something new at Gamestop.
The purchase was definitely worth it, if that helps. It's really not bad buying used or new Vita games at gamestop since they don't have any inserts and the cases don't appear to get touched very often lol.
I was going to buy it this weekend, yet the price jumped back to $40... I watched the anime so didn't want to buy it. But after finishing Danganronpa 2, I realized that playing the game will give me completely different feeling even though I know the ending already.
Just finished Danganronpa 2, the game is soooooooooo good. It is on the top of my list along with P4G to be the best games for Vita.
