ID DEFINATELY BUY IT!
You have skirmish, not to mention an online feature, the story line is better, and best of all the creatures arent robots! If you havent already, buy it! :yes
And don't forget Creature Isle, that game is awesome, although some of the challenges are annoying, it's still worth the money.
But you'll need Black & White first and the 1.10v Patch.
Well go for the Deluxe edition and have both.
It will look like s**t but so much more "real" feel.
Yes patch before you play but I would go for 1.2 as it contains all of 1.1 plus the extra MP bits that you may want later, 1.1 is fine if you never want to go MP.
