Now the xbox 360 and the ps3 are about 6-8 times powerful than the wii in specs, but they have to sacrifice a large part to produce hd which isn't too important for a good looking game as many members and I on vgchartz know. So this means about 30-50% of the power put in the game is to produce high resolutions.
Now this may make them only 4-5 times better than the wii due to the large part of them going to hd. Also you have to take in consideration these consoles are filled with huge bottlenecks and aren't as efficient as the wii.
So that makes me think with all of these factors the games are only going to look 3-5 times better mattering how good the developer used less power to produce the high resolutions. Now that isn't too much of a difference as people may think. This allows many wii games to look better than alot of ps3 and 360 games
Stop trying to get around your ban. I consider that "around the lines of saying its close to as powerful"
