Full Amazon statement:
You might have noticed that the customer reviews on the Spore details page were missing today. I wanted to let you know that we experienced a site glitch that resulted in the removal of the reviews. Amazon did not knowingly or consciously choose to remove the reviews. The team is working on resolving this issue now and restoring all the reviews on the site.All SPORE posts on gamezplay.org here...
Per our policy, Amazon doesn't censor or edit customer reviews and we'd only remove a review if it fell outside our guidelines.
