Nope, there aren't any games on the system that I would want to play. As for drawing comparissons to the DS as people did above, the DS (like thew PS2) is backward compatable with a lot of great games, plus it also is my portable alarm clock =)
I like The Urbz for DS the best of the launch titles, it wasn't rated high on IGN, but it's probably the game I have been playing the most lately. Then again, IGN isn't that reliable anymore I don't think, they gave Shadow Hearts a 5.5 out of 10, and it was one of my favourite RPG's of this generation.
I don't know, portable systems are important to me since I seem to be travelling a lot lately, I've been all over the world in the last 8 months. I am getting prepared for a trip to Honduras soon as well.
Anyways, I'm looking forward tot he Mistwalker RPG (The company founded by the old Final Fantasy development team before the Quest guys took over), Harvest Moon DS, Animal Crossing DS, Age of Empires DS, Final Fantasy Dawn of Souls 3, Lunar Genesis (I really love Lunar Legends, I didn't really like the original Silver Star Story, but the handheld version seems to be much improved in every aspect except music which is lower quality, even when the graphics are higher quality), then there's also Castlevania DS which is looking quite amazing, the new Legend of Zelda DS game. The DS also has a lot of interesting features emerging, the wireless internet connection could be interesting, as well as its wireless hook-up capabilities to the new Nintendo console out next year, then there is also that encyclopedia in the works for it as well.
On the PSP though, when it becomes worth buying, I'll buy it; otherwise I think I will just wait, maybe someone will get it for me as a gift.
