Please help me make a list of good games for the DS

well, i'm planning on getting a ds soon, so i want to compile a list of good games for the ds that i could rent/buy. this is my list so far:

New Super Mario Brothers
Some sort of Brain Age/big brain academy game
Yoshi's Island
Sonic Rush
Legend of Zelda: Phantom Hourglass
Pokemon Firered (GBA GAME) (Years ago I played pokemon red for hours on end, this this is a must buy for me!)

Pokemon Diamond
Final Fantasy? (never played a FF game before...)

I know I'm probably missing many games, so it would be great if you guys could help me out...thanks!!
