Which are the best Mario and Sonic online games?

I get asked this question quite a lot by visitors to the MarioSonicGames.com site. In my opinion, the top 5 online games featuring either Mario or Sonic (or both) are as follows:

  Super Smash Bros. Brawl Flash

  New Super Mario Flash

  Super Mario Sunshine 64

  Ultimate Flash Sonic

  Ultimate Robotnik Duels

However, this is a very subjective list, and I might give a different answer on a different day. Why not visit the MarioSonicGames.com site and check out the more than 150 Mario and Sonic games there to see for yourself which are the best ones.....
