Most of these tools seem to rely on the same idea: we have your data and we, being the domain experts of this data, know how to format it for you and how to create good prompts that are specialized for this context.
Do you mean that there aren't that many critically-acclaimed games nowadays (relative the the number of games coming out) because there aren't enough reviewers? I can't really think of many great, recent games that haven't had enough reviews or the attention they deserved. Sure, that might be some cases; but, in general, it just feels like we don't read more positive reviews because we're not getting that many great games.
I think that if the number of reviewers were to increase, the ratio between critically-acclaimed games and the total number of games coming out would still be very unimpressive.
