The Eurogamer staff have listed their picks for top games on any platform for 2002. Their top 50 includes commentary on why they've chosen the particular game, or in some cases why a game hasn't rated higher.
I can't really comment on any platform other than PS2 - but comments from site (eg. the comments for the top 10) indicate that the gaming community support the bulk of the decisions. In the end, Ico came out number one, surprising very few. In the words of the Eurogamer staff:
Actually, it was weird, of all the games in the top 50, ICO at No.1 prompted the least argument among the staff.
Other users have noted that the top 10 games lists 7 PS2 games, and not one PC game. It might not be the most powerful platform, but the games are still the best...
