No, there really aren't any quests per se, aside from delivering items for the towns people. In general, Animal Crossing is one of those love it or hate it things. It's a casual game through and through, and might just not be your kind of game. Perhaps go online and see if that aspect intrigues you.
Oprah is coming out in the next few weeks in Japan, and a US release shouldn't be far behind. Keep in mind though that the browser uses a DS cartridge for the browser and a GBA cartridge for caching and firmware upgrades, so the complete package will run you $35.
-New Super Mario Bros.
Note: I can recommend this to pretty much anyone.
-Castlevania: Dawn of Sorrow
Note: Timeless Castleroid style gameplay. Love the soul collecting system.
-Advance Wars: Dual Strike
Note: Great turn based strategy game.
-Mario Kart DS
-Racing game. Mario Kart. That should give you a good idea of what to expect here.
-Kirby: Canvas Curse
Note: Original platformer with some great ideas (namely, full stylus control to draw paths for Kirby to "roll" to). NSMB is the better platformer, but this is a good game nonetheless.
-Meteos
Note: Excellent puzle game. Puzzle game is the key here. You may or may not like it because of the genre.
-Metroid Prime: Hunters
Note: Only get this if you have a multiplayer WiFi connection. Singleplayer is only alright.
-Phoenix Wright: Ace Attorney
Note: Quirky little game that gets a lot of love from people who've played it. IN STOCK FOR A LIMITE TIME ONLY.
Here. Now or never.
-Age of Empires: The Age of Kings
Note: Turn-based Age of Empires. Fun, if a bit repetetive and complex on later stages.
-Brain Age: Train Your Brain in Minutes a Day
Note: Quirky fun little game to train your brain. Comes with Sudoku built-in as well.
