Here is my ultimate top 10 NDS games:

10. Mario vs. Donkey Kong 2 - good fun, but completed it in an afternoon

9. Lego Star Wars II - too many glitches! But still good fun!

8. Metroid Prime Hunters - I used to hate it, but I got back into it over the (exceedingly wet) summer

7. New Super Mario Bros. - can't get enough of those mini-games!

6. Big Brain Academy - fun AND educational: who'd have thought it could be done?

5. 42 All-Time Classics - a good round-up of games

4. Tony Hawk's Downhill Jam - This game is awesome, man!

3. Animal Crossing: Wild World - addictive, cute and inspired

2. Mario Kart DS - I fell in love with Mario Kart about 7 years back when playing at a friend's house.I am glad to finally own copy of this superb game!

1. Elite Beat Agents - THE best game ever put on a handheld system!

The ones I didn't include, but still love:

Hotel Dusk: Room 215 - it's not a game; it's an interactive mystery novel! It would otherwise be no. 1!

Electroplankton - not a game
