Interesting choices for the rest of the PSP games (all of them are games that I've played before [excluding Mana Khemia which I played in the PS2]). ^^
For PSP, my favorite games (so far, since I still have some games to play) would be:
1) The Legend of Heroes: Trails in the Sky
2) Kingdom Hearts: Birth by Sleep
4) Ys Seven
5) Crisis Core: Final Fantasy VII
6) Half Minute Hero
7) Gods Eater Burst
9) The 3rd Birthday
10) Corpse Party
12) Blazblue II: Continuum Shift
13) Tales of Eternia
14) Megaman Maverick Hunter X
15) Prinny: Can I Really Be The Hero?
Well, I still have more than 10 games that I intend to play on my PSP, so that list could change soon. ^^
@phoenixangel9 Gungnir is quickly becoming one of my favorite titles, as of the time I made that list I wasn't playing it.
By the way, are Mana Khemias load times as bad as they were made out to be? IGN completely panned the game for the load times. It gave it a 2.7 for Heaven's sake :P
@Spinnerweb Nah, if your PSP is the 2000 or 3000 model I suggest having at least some 300 MB of free space so you can install the optional data that greatly improves the loading times and add voices.
Out of this list I've played only GTA Vice City, Tony Hawk's Underground Remix, Crisis Core, Dissidia, and Metal Gear Solid . I might play few other from the list; maybe Silent Hill-Shattered Memories and Valkyria Chronicles 2. Nice blog ;).
@driton Yeah I can definitely recommend them for they are great fun! And I'm glad you liked, thanks for the support. :)
Crisis Core is indeed awesome. It breaks my heart that Valkyria Chronicles 2 isn't #1 though, you know :( :P
