Kenji Mimurao, creator of Cloud Strife (Final Fantasy VII): "I like Sonic and Bandicoot. I think they both possess characteristics that can be understood or can pass even without the game part of it. I also like the atmosphere of how it flows within the entire game."
Toby Gard, creator of Lara Croft (Tomb Raider): "...I like Sonic because he's so fast and weird. I like the lead character in NiGHTS because he moved so damn well."
These men have taste. Others who were asked the same question (Yu Suzuki, Shigeru Miyamoto, and Manabu Takemura) stuck to characters they created or were in the same game as the character in question. Brazen losers. So next time you sit down to a game of Final Fantasy VII or Tomb Raider 3, take a good, hard look at Cloud and Lara and remember that Sonic was part of the inspiration for these enduring characters. Neat, huh?
