DS Daily: Better with more

We've been on this whole "best" kick lately with our morning questions, and we've got another one for you today: what are your favorite multiplayer DS games? But we're going to offer some restrictions on this, however. You know we don't like simple answers. Let's forget a lot of the games that are more popular, particularly at our weekly Game Night, and instead tout some that people may not know as much about. Instead of talking about Pokémon and Mario Kart, tell us about Worms or something else. Online or not -- no limits there -- so long as the game is (in your opinion) a little less well-known!
