I knew early on Viva Piñata would be something special. I didn't know the game would eat my life.
Viva Piñata lets you build a garden and raise party favors. It's the dumbest premise ever, but the game is so wonderfully cute and open-ended (yet still features whacking with shovels so you aren't wholly emasculated), it's like a giant vacuum from which no time can escape.
I am on level 23 now. I have bred, and I have a pruned, and I have planted the Hazlenut tree. God help me, but I bought a hat for a video monkey. And even now I am telling myself to type faster because I am so incredibly close to level 24 I can taste it.
