The list is in that first post.  Click on the "Show Spoiler" or whatever it says to see the list.  From my experience, it's totally accurate but then again, I couldn't possibly have tried them all.  I have purchased games to play on my Vita (like Silent Hill Shattered Memories) based on my trust of that list and I've never been burned.

Thanks again!

Cross referencing with Basil Zero's list...

If you like rhythm games, get DJ Max. The games are pure quality. I think the only one available for the Vita right now is DJ Max Portable 3. I've played that one and it adds some interesting twists to the gameplay.

Edit: Since I've only played them on the PSP, I'm not sure if the Vita will feel well-suited for the game. Because the buttons on PSP are more mushy, they are easier to press and feel good for rhythm games. The d-pad works really well for this game also, oddly enough, since the Vita d-pad feels miles superior. It might not actually make a difference. Maybe I just need to get used to it and it'll be fine for me.

Here's a quick trailer in case you've never heard or seen the game:

Those pink bars on the left and right are new additions to the gameplay. It can also get very challenging. Totally worth however much they are charging you, unless you are not into this sort of thing. :P

Well I'd suggest these games

Tactics Ogre PSP - Remake of an SNES game, graphics and music are the same but they changed the gameplay in areas i'd mostly consider a plus. One of the best SRPGs ever.

Final Fantasy Tactics - if you haven't played another version. Not much new... and Tactics Ogre is better....

Persona Remakes... persona rules.

The Socom series.

God, I love Final Fantasy Tactics.

I bought it for the PS1 and completed it.  Then, I got the UMD for the PSP.  Last week, I bought the digital version for the Vita just so I'd always have it ready.  Gotta be one of my favorite games of all time.  Again, not for everybody but I don't care.  I could play that game forever.

I'm probably gonna get Jeanne D'Arc, too.  I own it on UMD but I never finished it.  It's a great game and, if it weren't $22, I'd have re-purchased it long ago.  I'm gonna get it, though.

If you like those two you should really get Tactics Ogre.

FF Tactics only exists because of how awesome Tactcs Ogre was...  They were made by the same guy... after how amazing Tactics Ogre was, Square stole Matsuno and his quest team to make FF Tactics.

Tactics Ogre in Japan still ranks as one of the best games ever.

I had Jeanne, never finished it either... got TO and FFT afterwords... got lost in the shuffle, then my PSP broke... and I got a 3DS over a vita cause it was $50 bucks cheaper and then there were a ton of DS games i hadn't played that looked good

Just found out that Tetris works on the Vita! Don't know when they added it but I couldn't be happier!  And Pursuit Force, too!?  Hell yeah!
