Harvest Moon Oh! Wonderful Life is the tentative name for the next Harvest Moon console game, this time on PS2. Supposedly not coming until 2006, although I think 2005 could be very likely, the game is based off the GC release but has some substantial additions, including: you may now have either a boy or a girl for a child when you get married, there are now upto 4 wives to court for marriage, and perhaps the best one is that you may continue to build up your farm even after the story campaign.
Now at first I said to myself, hmm another 'port' of an exlusive GC title to the PS2. But really, Harvest Moon games that have been released between consoles during the same generation have been largely based off the prior release. For instance, HMOL on GC was basically an enhanced port of the earlier PS2 release. So in this situation, it's just the opposite. I don't know how well HMOL sold, but maybe that was one of the reasons too, or perhaps that the time that would've been spent on a brand new PS2 release isn't possible because they're making Harvest Moon for the DS and PSP.
