What games should i get for 90 dollars?

I was gonna get m effect 2 via psn but I am gonna wait until I get my own ps3. I was wndering what psp games on psn I should get. I was thinking about mgs peace walker, lunar silver star, the 3rd birthday and in's creed bloodlines. but should I get bloodlines (I LOVE in's creed), or perhaps soulcalibur broken destiny (love soulcalibur too). or maybe the final fantasy 4 collection. idk which to choose. ideas? which ones are better?
