Ganbare Neopokekun
Tamagochi parody with lots of minigames that is also a recap of the evolution of videogames. Parodies of classic games such as Xevious, Star Wars (the Atari vector game), Kungfu Master, Ghost n Goblins, Bomberman, Dragon Quest, etc.
Card Fighters Clash
As everybody already said, a must have. Once you've sunk many hours into it try to track down Card Fighters Clash 2. It never got an english release but if you know how to play the first one you should be able to make your way through it (with a card translation faq for the new cards)
Snk vs Capcom: Match of the Millenium
One of the best portable fighters you can get. Some nice mini games to.
Magical Drop Pocket
Best puzzle game on the ngpc if you ask me and also the best portable version of Magical Drop.
Delta Warp
Another good puzzle game, somewhat overlooked.
Faselei
What Sacnoth did before Shadow Hearts. Excellent SRPG.
Metal Slug 1st & 2nd Mission
Sonic Pocket Adventure
Has anyone manage to find all the picture pieces?
Last Blade
Portable version of Last Blade 1 & 2
Gals Fighters
The fastest fighting game on the ngpc. Iori in drag.

I have an NGPC, but here's something I never knew: the batteries last up to 40 hours
Is this true? If so, wow.
Yes it's true, they last a really long time.
