Capcom has explained exactly why the Nintendo 3DS version of Monster Hunter 3 Ultimate doesn’t include online play. Monster Hunter producer Ryozo Tsujimoto revealed that the development team were having problems implementing a robust multiplayer experience on the Nintendo 3DS, so they decided that they shouldn’t release something that didn’t work well.
“To put it frankly, when we were developing the game we were looking into it but there were some places we were unsure about. We didn’t have the correct techniques to get it to work. We decided we probably shouldn’t release something that didn’t work well. We didn’t want to lower the quality of the game.”
