Worthwhile DS Games

I just recently bought a DS online and it should arrive any day now. I already have Pokemon on standby, but what are some other worthwhile games? Thanks.

eliet beat agents is pretty much the soul purpose of buying a ds
Phonix wright:ace attorney
Final Fantasy III..........
pretty much what everyone said here the pros and cons about ds are
VERY LIMITED AWESOME GAMES FOR DS
and that about all the bad things
but a ds is more fun if everyone has one. you can do some pretty fun stuff with pitcochat with the right friends and the ds has good batterylife
