Poll: PSP game or GW2 :s

 Hey guys I'm sorry for the previous blog post :S I guess it was just wierd to see Left 4 Dead go Multiplatform and I kinda directly wrote it here :s
Ok but back on my topic.
I'm making a little poll to have an idea for a small purchase I wanna do... I have the choice between a new PSP game or Geometry Wars 2 on XBLA.
I wanted to know your opinion if it's one or the other :s
If you choose PSP game can you please specify?

I currently own Manhunt 2, Monster Hunter Freedom 2, Both GTAs, PES 5, DJ Max Portable 2, Lumines 2, Silent Hill Origins and God of War Chain of Olympus.
Was thinking of Metal Gear Solid Portable Ops or Crisis Core :s

Thanks :)
