I enjoyed it alot at first, got bored with it about a week later, then right when I was about to give up I met some cool people to hang out with in the game. So IMO unless you can get into the "social" aspect of the game there isn't much there.
The 3DS eStore is going to start releasing new games on Thursdays. I think that starts next week (or whenever the next batch of games are coming out). In the meantime, ten E3 trailers have been made available for free through the shop.
