I got the 31 sample requirement from my stats textbook, and that is the bare minimum to be able to fairly safely say that one should be close to the whole with an estimation. By what you said then, no game(according to gamerankings) has enough reviews to have an ideal representation; The 360 version of GTA IV doesn't even have half of 120. I know that you said 120 was just the ideal number, but having less than half of the ideal number, to me, would imply that there just isn't enough information(# of samples) to get a very reasonable and probable answer. I do have to ask though to anyone who may know; about how many reviewers were there when OoT was released as compared to now? I ask this because if there were simply not many reviewers then as compared to now, I don't really think it would be fair to count the small number of reviews against OoT as much since more reviewers just weren't there. This doesn't completely excuse OoT for 32 reviews, but it would explain why.

I'm glad someone has their statistics book with them. I had a look at the t-distributions on Wikipedia. Here would be the adjusted analysis of the 95% confidence intervals, adjusting the numbers for the number of reviews.
GTA IV (PS3) 91.28
GTA IV (360) 90.33
OoT (N64) 91.00
SMG(Wii) 91.19
Now adjusting for statistical outliers, i.e. reviews that are too unusual to be counted we get the following:
GTA IV(PS3) 92.61
GTA IV (360) 92.44
OoT (N64) 91.00
SMG (Wii) 91.19
So essentially the same results as I obtained before, although slightly more accurate now :)
EDIT: Probably should make it clear that these numbers are the reviews scores that we would expect 95% of all reviews to be higher than. So we expect 95% of all reviews for GTA IV (PS3) to be 92.61 or above.
