I think it stinks that you have to buy multiple copies of the game to play head-to-head. It supports wireless multi-card play, but not wireless download. So even if you have more than one DS, you either have to pass one of them back and forth, or shell out more money for a second copy of the game.
Was trying to find a game that both my kids (boy-6, & girl-10) could enjoy. My daughter has played and seems to enjoy it for a little while. I've played the game, too, and relished in the memories these simple board games brought back as a kid. Battleship is pretty cool as far as graphics. I am disappointed that you can't download the game to another system, but I find that is the case with most of Nintendo's games.
Overall, it's a pretty good game, but might not keep your attention for long.
I purchased this game for my son. He has played all four games in the traditional versions, and loves the DS games. The only problem that both he & I have is with the Connect Four game. The black pieces are hard to see because the background is also dark. And, at the end of your turn, the stand rotates to reveal the opponent's view, which we find confusing at times.
