When using a sample, the issue of sample validity comes up. The idea is that the sample should be representative of the larger group. There is no validity when it comes to this.
There is no industry standard (in fact, I can point you to several sites which use a different rating system)
End of discussion.
If you are so concerned that different site use different methods, then just use one site.

5632 readers gave the game an average of 9.2 out of ten. Since there was only one rating system used, you concern should not be a problem. 5000+ is more than large enough sample size to get a fairly accurate measure of the general feeling gamers have for ME2.
If you are going to try and tell me that the opinions of 5000 people who played ME2 and use the same IGN rating system can in no way be used to represent gamers who have played ME2 as a whole, you are being silly.
O RLY?! The Opinion of 5000 individuals is representative of 1.5 million individuals who bought the game (not to mention the demographic variation which is impossible to discern)? LOL!!!
uummm... yes that is exactly what I am saying. It will not tell you how every individual person feels about the game, but it will give you a good idea of the general view that the 1.5 mill gamers have on the game. This is not some new concept. It is impossible to interview an entire population, so studies interview a small percentage of the population in order to represent the whole.
The biggest factor is to make sure the sample group is an accurate representation of the demographic you are targeting. The only demographic in question is gamers, since that is who the game was made for. Since very few people who have not played ME2 would review it, it is fairly safe to say the 5000 reviews fit the demographic in question.
You clearly failed Statistics 101. Do you even know what a "representative sample" is. You non-probability based sample of 5000 has no "external validity" whatsoever. It's like saying that the choice of the individuals living in a certain neighborhood/city in voting for a certain state official
is representatiive of the entire city/state itself.
Also "demographic of gamers"....seriously?!!! LOL!
