I found this game to be utterly boring, after all the hype it received and potential it had I was expecting a very interesting game but what I got was mediocre at its best and utterly boring at its worst.
The concept is good but what has been delivered is too rushed and too linear. The design of your creature has no effect on its abilities, give it 4 arms and 20 legs and it will work no different then one with 1 arm and 1 leg.
My conclusion is that the idea is good but the execution has been an absolute let down and is not worth buying unless they give you money for it.... and cake.. . Who knows maybe spore 2 will be better.
