[quote name='hootie']Would a NGPC be worth getting, or should I avoid it?
I already have a DS Lite, if that makes a difference[/quote]
I'd say so. Even if you don't like fighters, there are plenty weird little quirky things if you look around.
In addition to the Samurai Showdown 2, Metal Slug 1 & 2, Fatal Fury: First Contact, Match of the Millenium, Card Fighters and Dark Arms recommendations, I would also suggest Biomotor Unitron, Cotton, Neo Turf Masters, Puzzle Bobble Mini, Magical Drop, Dive Alert, Baseball Stars, Faselei and pretty much any fighter on the system. It's a great little machine to get some milage out of.
