I rewatched the Beijing opening ceremony last night, and I have no qualms with saying that it was a better opening ceremony than London in terms of its visually spectacular synchronisation. However, in terms of the overall games, London is the best ever in my opinion. The incredible atmosphere was felt around the world through their TV screens and the crowds were amazing. Their organisation was incredible and it just made you feel good. The closing ceremony was also like one big party.
London was better yeah, but i still Think Sydney is the overall best games that i know of.
Barcelona and Atlanta was awesome too (barely rememember Barcelona tho) i Think, the best thing sports related from 1992 was clearly US Dream team
