Monster Hunter 3 (Tri) is an action coop game that was developed by Capcom and released for the Wii in 2009 (Japan) and 2010 (USA and Europe). As we can read in Wikipedia, the game was originally planned to be a PlayStation 3 title, but due to high development costs for that console Capcom instead decided to develop it for the Wii. Thanks to Monster Hunter Wikia, we can see many concept artworks from the official Hunter Encyclopedia 3, that show early versions of the MH3 monsters and various unused enemies (that may be revived for a possible MH3G expansion).
