I've always heard from friends and others that Sonic was becoming way more popular than Alex Kidd; therefore, Sega replaced there former mascot, Alex Kidd, with Sonic. But I've also heard that Sega made Sonic for the purpose of replacing him. So I was just wondering...Which is it? Did the fans just like Sonic more, or was it Sega's decision all along to replace Alex Kidd with someone new?
