Getting a DS lite! Help me pick out games!

[mauve]

Instead of doing something SMART with my tax refund, I'm blowing it on video games! I'm such a responsible adult. I've already decided on spending some on L4D2 or Mass Effect for my PC, and with the remainder I'm thinking of getting a DSlite. Problem is, I haven't owned a handheld system since I had a GameBoy Advance as a teenager, so I haven't been paying attention to what's come out. Recommend me some games!!

Here's what people have recommended to me before:
Phoenix Wright: Ace Attourney
Elite Beat Agents
Mario and Luigi: Bowser's Inside Story
The World Ends With You
Legend of Zelda: Phantom Hourglass
Professor Layton and the Curious Villiage
Final Fantasy: Revenant Wings
Pokemon Something-or-other (I've never actually played a Pokemon game before, so..... *shrug* )

You guys' thoughts? Am I missing anything? Are any of these as awesome as they're said to be? Am I crazy for buying a DS lite right now?
