Hi, I have a 360 and a wii
The main reason i got a wii was for the children, 360 and ps games are a little more blood and guts/war /crime.
nintendo are more sweet and innocent, nintendo also have the knack of making very playble simple games.
Graphics are better on the ps2 let alone the ps3 and the 360 but it really doesnt affect the gameplay.
pros wii
anyone can play straight way, the controler is easy and people who dont normaly play video games can easily get involved.games are thin on the ground ther eare only a hand ful worth getting to be honest.
tiny neat box
internet browser
abilty to buy cheap games via the web
if you play the games in the way you are supposed to it is a physical work out as well (also a con :-)
gamecube games work fine (�2 on ebay)
you can play flash games on line www.wiicade.com
cons
its is more family /friends oreintated so you need to buy extra controllers 2 per person and classic if you want some of the older games.
games are quite simple and although have replay value you can finish pretty much all of them on the day you buy them. (if yur new to gaming ignore that)
after buying a wii and a few games and controllers i find my self now a month later playing the older games from nintendo store which dont use the wiimote.
and im talking really old donkey kong simcity etc
just down to good gameplay.
worth buying yes totaly, but the wii mote the main sales point does lose its wow factor quite soon,
if you want to stay in a room and play games on your own all night then a 360 or playstaion might be better for you, if you want to play with friends and are more intersted in gameplay than graphics than go for the wii
oh the wii gets more use
