Top 5 must have PSP action games for the PS Vita

Now there are plenty of great PSP games to load onto your Vita but there are only a few that truly stand out as must have titles. Here's a list of five must have action games that are great and worth loading onto your overpriced memory card.

The Warriors is #1? These dudes are crazy.

ratchet and clank size matters with the second analog stick it can be a lot easy for the game

[GenericNameHere]

Got MM:MH, and it's freaking fantastic on the Vita!

[abzdine]

Killzone: Liberation is a really really good game on PSP.
And for Peace Walker there is an HD version on Vita already..

[Muigi]

no there's not

[Knushwood Butt]

Peace Walker rules.

[himdeel]

Just got Peacewalker for the Vita. Man it's so good! I just wished the online still worked.

[Knushwood Butt]

The online component is great. Particularly the co-op.

I recommend the HD remake for PS3 or 360 (I think?).

[Protagonist]

Even though Army of Two: The 40th got terrible reviews ( which I never really understood why ) it was one of my favourite action games on the PSP. I completed it and enjoyed it a lot and would love to play it again on my PSVITA.

[HammadTheBeast]

Persona 3 Portable. I don't care if it's not an action game, if you don't have it right now, you need to play it.

[Protagonist]

Just completed P3P for a second time but this time with the fenale protagonist on my PSVITA.

In my mind this is probably the best game ever made.

[Xperia_ion]

That game I would buy over and over just to show my love for it.

[Hicken]

I haven't finished the female run through yet. I've only got the last boss to beat. I just hate the idea of the game ending; it's so good.

Doesn't PS Vita already have MGS HD Collection?
If true then why would it need Peace Walker?

[jocelot]

because the mgs hd collection doesn't includes pace walker =)

[Protagonist]

Peace Walker is not included.

[DivineAssault]

i agree with most of the list but the warriors? i dont think so.. I would put Castlevania in there being that it includes SOTN & Ronodo of Blood as well as the main game for $15..

[Ultr]

God Of War Ghost Of Sparta, best PSP game ever

[ZHZ90]

@jocelot & @Protagonist,
Ok sorry my bad but I know that MGS HD Collection is on PS3, Vita & X360 anyways thank you for letting me know about it
