Glad your enjoying Peace Walker, its easily my favorit PSP game. And its sequel ground zeroes looks superb, just make sure you get the true ending to peace walker before your done with it, its well worth the trouble.
Playing: Metal Gear Solid: Peace Walker HD
Not counting the MSX games featured on MGS3, I'm playing the last game to be featured in the MGS HD Collection on 360. Let me say, this is a very well done handheld (PSP) to console port. The game not only looks better in HD, but the way they re-coded the game to make it work with dual analogs making aiming much better (granted, I never played the PSP version, nor do I own said system, but being an N64 fan, I know what playing with a single stick is like).
In a rather geek-out moment, there is something so badass hearing David Hayter and Steve Blum in the same game, both having very awesome voice talent making their characters sound even more badass.
Replaying: Eternal Darkness and Wind Waker
I thought, why not take another branch with this game? I already beat Ulyaoth's path, so I'll go with Xel'loath's path now. Funny, since I'm still playing a Metal Gear game, quite a few of the voice cast in this game make it feel like a Metal Gear reunion. Jennifer Hale (who did hundreds of roles like the female versions of Jaden Korr and Commander Shepard, but in MG she's Naomi Hunter and Emma Emmerich) as Alex Roivas and Xel'loath, Paul Eiding (again, like Hale has a lot of voice work, like Judicator Aldaris and Max Tennyson, in MG he's Roy Campbell) as Paul Luthor and a corrupt monk, Kim Mai Guest (Mei Ling in Metal Gear Solid) as the Cambodian slave girl Ellia, and David Hayter (everyone knows who he is), while not in big roles, still played as background Roman soldiers. Then again, considering Silicon Knights released MGS: Twin Snakes, I shouldn't be surprised.
I've also been re-playing some glimpses of Wind Waker. Still a good game, left at the part where Link has to go triforce hunting and paying that greedy bastard, Tingle.
Well, that's it for me. On a side note, my dad picked this up:
