In Nintendo Power's 20th Anniversary Issue the magazine printed a "definitive list" of the 20 best games for each of Nintendo's eight gaming systems (sadly, Virtual Boy was not included). The reason for there being eight "best of" lists instead of one big list like the 100 Best Games of All Time or the Top 200 Games was so that the games could be judged more fairly. The criteria for what made the list was impact, fun factor, and long lasting appeal.
