My parents bought my brother and I a dreamcast when we were very little, and we would bring it to our Aunt's cottage and play games such as Ooga Booga. I have to say we were 7-11, we had no grasp at the concept of this game but it was always very fun to play. From being on the shallow island, to the Volcano, or Boar soccer field it brought lots of enjoyment to us, no objective needed.
While I do feel like a lot of the gaming community would love a sequel, I believe it wouldn't hold up as players today look for unlockables, challenges, levels, easter eggs, and so on, that they won't be able to enjoy a game that is just pick up a controller and have fun with no objective. This game will be fondly in my memories forever.
