Do you expect 360/PS3 graphics on a Wii? There is no need to argue about the pixel count on a game that is designed to be played and enjoyed. If grpahics are all you buy a game for you might be better off taking art as a hobby rather than gaming.
To be honest this review sums of Tiger '09 perfectly. The small mention of graphics is good journalism, as Tyler has said, because the graphics on a Wii game are probably the least important feature. When I'm playing Tiger with my friends we don't stop to take in the scenery, usually because there's at least 4 of us and everyone wants a turn.
Stop whining and get out their and enjoy the games!
