help on the Wii

Hi guys havent posted on gamespot for a long time but im thinking about getting a Wii. I spent alot of my childhood playing N64 games with friends and at home, and have a list of classic n64 games that i would love to play again on a new console, im guessing not all of them will come but how many are there to download now, a few favourites would be diddy kong racing, top gear rally, mario 64, goldeneye and lylat wars. Would they have any more features compared to there original counterparts (i.e online play, rankings and so on)? Finally what are your views on the Wii as a whole so far, how are the games range of accessories etc...

Thanks in advance
