comparing the graphics between the wii and 360/ps3 is pointless.
the 360/ps3 made games will beat - on just resolution- the wii-
look at the video of RE:UC (resident evil:umbrella chronicles) on IGN..that is 480p resolution, but cut down for video, those graphics look good enough for me if the GAME is good.
Great graphics does not sell the game. GAMEPLAY sells the game if it has good enough graphics, if it has poor graphics, it might sell decently, but not as well as it could have.
the wii is selling due to 2 things
1st. PRICE 250 is a HELL of a lot easier on the pocket than 400 or600 dollars.
wii wins on VALUE.
for most AVERAGE casual players using the wiimote to play game is more fun than using a standard controller.
wii wins with the average casual player on FUN FACTOR.
i've personally had 5 different couples from my INLAWS(who are in their mid60's) to my friends get interested in buying the wii just from playing Tennis and Bowling... and my brother-in'law's father interested in it for Golf.
