Question about picking up games!!!!

So here is the deal:

I am leaving in Israel and my father is going to the USA on April 2th. I looked at the released dates and I have found 14 great PSP games. So my question is this: what are your top 3  PSP games form the list? I will give you a list of 14 games and please order them from top to bottom so I can decide which game to pick because, for my taiste, all these games will be great so here we go:

1) Tom clancy's rainbow six - vegas.

2) Ratchet and Clank - Size Matters.

3) Ghost Rider.

4) M.A.C.H

5) Major league baseball 2k7

6) Valhalla knights

7) Burnout Dominator

8) Full auto 2 - battlelines.

9) Call of duty - roads to victory

10) Coded arms contagion

11) Prince of Persia - Rival Swords

12) Tom Clancy's Ghost Recon - Advanced Warfighter 2

13) Dragon Ball z - Shin Budokai - Another road.

14) Rocky Balboa

So this is the list. For my taiste they are all great games. So please, tell me which 3 should I take and in what preference are them

Thanks in advance

My opinion is mostly based on what Ive *seen*, not played  as most of these games are only available in preview form on gamespot. That said I recommend in decending order:-

1:- Ratchet and clank: size matters - the preview given by the developers themselves made the game look absolutely awesome

2:- Valhalla knights - Set to be one of the better rpgs for the psp until FF7:Crisis Core retails, althought the people who have actully spent time with this game have very mixed feelings about it ( some say its great others say it sucks)

3:- Ghost rider - appears to play like God of War and Devil may cry....nuff said:D

I'd say Burnout, Ratchet or Clank or Rainbox Six Vegas
