So you got your DS? Then you need to get Meteos
The multi player is great with up to 4 people plying separately on their DS. I always like to do LAN PARTIES at my house but I must say I never thought of that from all the DS games we had, including Metroid, we couldn't stop playing Meteos. That's how good it is.
So if you have a DS, you got to have this game, its a never ending challenging game.
