Firstly, in statistical terms OoT does not really have enough reviews for those reviews to be a reliable indicator of the games quality. Worth noting that basically no game does but the like ot OoT are particularly bad and no real meaning can be obtained by looking at the "average".

Secondly, even looking at the "raw" scores there is very little difference between any of the top ten. This is particularly so given the first point I made, there is no statistically significant difference between their raw scores and no conclusions can be made about which game is better. Sad I know.

I thought that in statistics you only needed 31(random..ish) samples to be able to safely say that you have enough to represent the whole.  If true that would put OoT at (barely) enough reviews to say that its current percentage is a good representation.

You can get by with that number but you'd rather not have too. Ideally you'd have at least 120 reviews (If I recall correctly, I don't have my books with me at the minute). The lower the number of reviews the wider the confidence intervals must be. My analysis was flawed because I applied an identical confidence interval to all games (95% confidence interval, represented by +- 1.96 standard deviations from the mean). Had I not done that the OoT result would've been a lot weaker (and so would the other games but not to the same extent).
