PSP is better. DS. is better.
Nintendo's handheld market software:
Hrmmm... Most of us that have social skills and/or free space large enough to raise an animal will never pick up Nintendogs. Personally, I'm 26 years of age, and I don't care a lick about anything related to Pokemon or tamagatchi-pet related. The only way I'd ever play something like Nintendogs is if there were a new series in which one could raise a preying mantis or a scorpion. Teh kiddy games are not something that most of us mature gamers are really going to care about in our personal gaming experiences. The indirect importance of these two items, to the world of DS owners and fans of Nintendo, translates to meat-and-potatoe sales for Nintendo. I do not, nor shall I ever care to play any of Nintendo's very kiddy titles, but the existence of kiddy titles does not negate the awesomeness of other DS software.
Personal DS Experience:
I've put in 13 hours of complete fun exploring the castle in the new DS Castelvania.
Import Electroplankton kept many of my friends entertained in its trippy way; other friends of mine didn't care much for it.
My girlfriend and I can't get enough of Metroid Pinball, and I'm sending fan-mail asking for more.
If I could afford a copy of Phoenix Wright: Ace Attorney I would gladly pay the circa $70.oo American that it would take to get it to my door.
I believe the same thing for Ouendan & Doramon imports.
I also can't wait for wireless Tetris. MarioKart is already here, and I'll probably buy it when it gets to $20.oo.
...........I am sure that both the PSP and the DS each offer unique gaming experiences. However, there is one system that I prefer from the outset.......one that already has a huge library of GBA games. The only appeal the PSP has to me is maybe the ability to do the many things my laptop does. The winner there = my notebook computer.
You can't play it [Nintendo DS] in public.
I'll always have something to play on the DS, and I'm secure enough with myself and my self image to know that I don't have any qualms about playing the DS in public. I just want to keep aware of my surroundings so that I don't get robbed/mugged.
Those who can't enjoy themselves in public because they are concerned about their image should to act and feel like that have a pair. Indeed.
