I've said it before and I'll say it again. The PSP desperately needs a $20 budget tier of games. The day this game came out for PS2, it only cost $20 (currently, it's $5 at www.bestbuy.com). But for PSP it's $30. There's just no market for this game at $30.
Same goes for Midway Arcade Treasures. A $20 game for PS2 is $30 on the PSP. Sorry Sony, but that $#@!'s just not gonna work.
