I figure the full version (which I'll surely play in Sept) will probably be too complex for my 4 year old, but she loved the creature creator. We spent an hour tonight before bed making a dinosaur and a purple hippo all at her instruction. "No
those eyes.
That color, etc." She'd give the creature commands in the
Test Drive area and I'd click applicable buttons to make it look like the creatures were interacting with her. She also got a kick outta the babies. I can't imagine what we can make with the other 75% of the creator elements not included in this free trial version. I'll be getting the $10 one for sure this week, and try not to waste too much time at work.
I'm not normally such a shill, but this is gonna be HUGE.
