Will Spore be a huge hit or a sleeper? This is up to you to decide. I personally believe that it will reach beyond what The Sims series has done. With all of the editors built into Spore, it’s a huge sandbox where almost no rules apply.

Four analysts polled by TheStreet.com predict sales of Spore will range from 3 million to 5 million units this year.

“I think Spore will do at least 3 million units as a packaged product, and if it’s as good as it looks, it has the potential to do twice that,” said Michael Pachter, an analyst with Wedbush Morgan, which does not own shares or have an investment banking relationship with EA.
