IGN Wii guys thanked in the Conduit's credits. Possible bias in review?

IGN gave the Conduit its second highest review score to date.  I just beat the single player and noticed that Matt Cassamassina and Mark Bozon are thanked in the credits.  There are other names underneath theirs that I believe are also IGN Wii staffers.  I smell a bit of bias.
