Harvest Moon was already released on SuperNES and N64. Unfortunately, the N64 version never hit the European stores, while the SuperNES version was very popular.

This is what the site reads on Harvest Moon:

Harvest Moon: A Wonderful Life will span a lifetime on the farm and follow the drama that goes with it. Not only must you build and successfully run a farm, but you must also build a successful life with family and friends! This new Harvest Moon experience will take the best qualities of the series and add more�more animals, more vegetables and more drama! What sort of life will you live?:

• Non-linear game play, making each game a new adventure!
  
• New vegetables and the ability to make hybrid vegetables!
  
• New farm yard animals!
  
• Get married and raise a family!
  

The game will hit the stores in the second quarter of 2003 in the US and Japan, but it's unknown if and when the game will come out in Europe.
