“It’s something that we’re looking into at the moment and there are a few factors to consider. Firstly, Monster Hunter isn’t as popular in the West, so it might put people off. Secondly, Japan doesn’t have Friend Codes, so Capcom run all the servers and the monthly fee is essentially to pay for those costs.” – Chris Kramer, Capcom USA’s Senior Director of Communications and Community
To be honest, I’m not a fan of online fees at all. With that said, I’m sure that many gamers aren’t. If there are no additional charges for Monster Hunter 3, that’d be a huge plus in my book.
