Need help!!!!!!!!!!!!!

I have 20$-40$ to spend on a PSP game. Should I get Tomb raider Anniversary, Prince of Rival Swords or Syphon Filter: Logan's shadow.

P.S. I don't know about Logan's Shadow because it cost's 40$ I would like something that costs 20$ or 30$ mch more.

syphon filter seems to be good i haven't played but i have the 3 ps1 games, and they are great.

i loved rival swords... it's the remake of two thrones for xbox and ps2.
