Well I got Spore today(and a free Spore tee-shirt). So here my first impression on it. I am at Creature Phase now, so it not going to be much, but here are the pros and cons for now:

Pros: Creating vehicles and buildings is pretty fun, through not as fun as creating creatures, but overall creating stuff in Spore is great and fun, great artistic design, sharing stuff on Sporepedia is cool. Some interesting ideas in the phases that I play.

Cons: The gameplay in both Cell phase and Creature Phase are a little shallow, and Cell Phase is boring.

Well that it for now. So far it great for the most part. Too bad both Cell and Creature phase are a little shallow through. Hopefully the other phases are going to be better.
