Right, I think Ive got all that. And I approve 
So if I do understand correctly (which I rarely tend to do):
1)User gives an opinion out of 100%
2)Their Percentage displayed as rating out of 5 'Wii-Related Objects'
3)Percentage put into average game rating
Righty-Ho, yeah I think that is a good idea. But you mentioned rounding for a users percentage - would you leave their precentage unrounded when its added to the 10-'star' figure? You say that you round for the User, but would you for the total average? Because a rounded average wouldnt be as good, in my opinion. LIke 3 users vote (lets keep it simple) 74%, 80% and 90%. Their ratings become 3 1/2, 4 and 4 1/2. But in the 10 'star' one, this could either become 8 Stars (rounded), or more accurately, 8.1 stars.
I think the example makes sense
haha
Yeah, in other words, will you round the stars, or keep them as blah and a bit?
And yeah the last bit of my comment was just for when the site grows a bit, it may be worth it to show what a team of gamers think, and show what the user thinks, so as to have two seperate appeals - if you consider yourself like that team, theres your one. If you think youd relate more to other users, then the average is for you
