MGS: PO or Kill Zone Liberation?

I want to sell my GTA:LCS for a new game. What game should I get between MGS:PO and Kill Zone?MGS: PO or Kill Zone Liberation?
killzone is cool but I heard portable ops was great, if you like metal gear then get that.  if you willing to give killzone a try then do it.  It reminds me of a mini Gears of War in some respect. cuz you can hide behind stuff and sshoot back.  I like them bothMGS: PO or Kill Zone Liberation?
I think you wont get disappointed with one of them..

I'd go for MGS PO .. but Killzone is a great game either according to the demo
killzone is fun, but the later levels were so frustrating that i almost had to buy a new psp.
MGS:PO Is sometimes frustrating, but for me its always fun.

i never played killzone but i own MGS PO and it's very fun and addicting.
Portable Ops
get both :D

Do you know why he is asking you? Because he can only afford one
I enjoyed Portable Ops a lot more so I advise that one.
I found Killzone the more enjoyable to pick up and play, MGS seems to take longer to get into and is more sluggish to play, making it less enjoyable.
First of all, I would never sell VCS in the first place, but its your choice. To me, I would definitely pick Portable Ops, although they are both awesome games.(I just felt like bowsing topics on the last few pages. This one was on page 1066.)

i never played killzone, but i no mgspo is amazing, the graphics are great for the psp, and it has first person aiming like other mgs games, and your big boss again so its sick
Obvious answer: Portable Ops. Killzone is fun as hell, but if you have to choose, that's a no-brainer. PO.
MGS:PO lasts longer and is way more fun
