I am a huge Sega fan, but I have to admit that Alex Kidd in Miracle World in my opionion is a good game, but not on the level of SMB. To me SMB is a much more fluid and fast game, one that can be played in shorter bursts. While I like Alex Kidd, It for me is a more methodical game, one that has to be enjoyed in longer periods of time. I for one think that while the game is good, it is definately in a different league of gaming that is not for everyone. I always didnt get the mascot Alex Kidd...to me he looks like a bad Plannet of the Apes reject.
