Most of the enjoyment will come from playing against a friend, which is why we welcome the ability to play this game in a four player system network using the single cartridge "Download Play" function of the Nintendo DS. On the downside, this is the only way to play Worms. Why is this a bad thing? Worms gives players the opportunity to customize their own team with unique Worm names and other settings. But without the ability to link two or more cartridges together, those who spent the time creating their team won't have the opportunity to use it against anyone but computer AI opponents.[/b]
