This was the height of the Harvest Moon franchise and was quite simply the most addictive game I have ever played in my entire life lol. I don't know how on Earth I managed to wrench myself away from it in the end, but I do know it couldn't have been easy :P
Second place goes to Tekken 3.
My bestest friend is hooked on this game too! What a small world. lol
I might take this thread and try some of these games now that I have a proper PS1.
