Did... Yahtzee actually play the game though? I know I found playing friendly (herbivore, social, etc) I had it quite easy. Playing as a herbivore, your only chance of defeat is if an Epic creature comes after you. Otherwise, your chance of being mauled is 0%, because everything else can simply be walked up-to and sung to.
Now I'm not saying he didn't try the game out, but if he did, then why did he only really quote all the negative aspects from the forums and stuff? Why didn't he mention all of the bugs or the fact that the game is hardly as customizable as it seems? If you want the most powerful creature (either in friendliness or in ferocity), you only have a few things to choose from. Nothing is based on looks, it's all on stats if you want to successfully beat the game. He also didn't care to mention that all other tribes in the Tribal stage were one creature, nor did he mention that all civilizations in the Civilization stage were just copies of your own creature.
