i want to buy a console for the family and i believe wii is the best for this.

i brought a wii in december but when it got ordered it seemed used so i gave it bak with my refund and just kind of put me off buying the wii. also ive heard people get fed up of it after playin it for a week or 2 so im just abit puzzled as to is it a waste of money or worth buying.
edit

it was the limited edition Black wii i got in december

im a football, and wwe fan and i know the graphics arnt as great on the wii then the 360
but i want to buy a console thats more family oriented and if its DEF worth buying?
