i forgot how the quote went..
it's like hitting a tennis ball against a wall, it's fun, but it's way more fun w/ a partner.
do you want a partner jim?
ah forget it!!!! it's been a while since i saw american pie.
now that i told a really dumb joke, the zelda game itself is standalone, and if you link up with other players, you get different quests to depending on number of other players linked up. the four swords part of the game is supposed to be really good, and was mentioned as worth the price of the game just for that feature.
as for the zelda: link to the past part of it, it's a damned near perfect if not perfect port of the super nintendo game.
check out either ign.com or gamespot.com and look for the review (too lazy to link)
