As much as I wanted to like Viva Pinata, due to its cool concept and creative art style, I couldn't get into it because I felt like the first few hours constantly bombarded and overwhelmed you with new information instead of gradually introducing you to it, and then the time after that was a lot of waiting around for stuff to happen (i.e. births, new pinatas to visit, etc). Not to mention, the area you can terraform is relatively small. And how many times can you play the boring mating games?
Also, I never quite understood how to stop fights between 2 pinatas.
