that package is pretty good. i dont see anything you in there they force youto buy that isnt worth the package price. except maybe the memory card, i never needed on when i had a wii.
based on what your looking for an xbox360 or a PS3 is not a good choice. wii was the right console for you and your wife.
as for other fun two player games, the possibilities are endless with wii.
also lots of people will tell you to get mario galaxy, personally i dont see what the big deal is, its just another mario game to me... but usually id get flamed for a comment like that lol. it's up to you.
its true the wiis graphics suck but thats not why u buy a wii. most wiig ames look worse than last gen games because developers are LAZY. but it's capable of slightly better graphics than an original xbox.. or so they say.
