On Thursday, I bought a game for my xbox 360. It was only $20, the game was Viva Pinata. Now, before you bash me for buying a childish game like that, try it out first. I found it to be very good, I have about half of the achievements, including playing 10 hours real time. I have played this game non-stop and it is a very fun RPG. For $20, why don't you give it a try, I did, and I love it.:)
Viva Pinata has a lot of strategies and RPG qualities. Its fun and hard at the same time, I recommend this game to everyone, young or old.
