I tried this with ChatGPT deep research and got some odd results. Query terms are:
generate a list of the best 50 Game Boy Advance games of all time, using critic ratings from well regarded sources, combined with user ratings, and giving extra weight to games which have aged well and are considered innovative and still fun today
and
only official released, no remakes, use the expert curation as part of the aggregate score
First of all, why is ChatGPT arguing with itself constantly while making this list? 
Bizarre. Never seen that before.
