I just got a 360, and i bought Project 8 as my first game. My little brother wanted something easier to play so i got Viva Pinata for him also. Even though I REALLY wanted to get Gears of War :(
Its a great game for any age and even teens and adults would like it too.
It is really kiddie but it takes alot of strategy and thinking.
Viva pinata is a life simulation game in the same kind of style as Harvest Moon games. You must care for a magical garden on the mysterious pinata island and attract various species of Pinata to come and live in it. Now, this sounds pretty easy, but the game can get quite complicated. Players must meet each pinatas requirements for it to become a permanent resident, this sometimes means having to feed it a pinata that is lower down in the food chain or providing the correct environment. Players must also protect their garden from 'sours' who can completly wreck your garden.
All of this may frustrate younger players (as it did my 7 year old cousin!) and it may also upset them when their favourite pinatas get eaten or get sick and get killed by the creepy Dastardos (a grim-reaper type character). There are over 60 species to attract which requires alot of time and effort! Players can also trade pinatas and other items with their xbox live friends, so it is entirely possible to get every pinata.
The game looks really lovely (especially in HD) and the framerate usually keeps up with all the action. I highly recommend this game to anyone of any age
who enjoys a challenge.
