Years in the making, Will Wright’s Spore peeks out today with the release of the Creature Creator. The free download is a toolkit for designing the life forms that will inhabit the Spore universe when the full game launches on September 7.

Spore, the highly-anticipated new game from Sims creator Will Wright, is set to go on sale this September. The game, which we described in detail in this article on Wright, was supposed to come out last year. But the delays arent a huge surprise considering that Wright has invented a game that essentially lets players manage the evolution of creatures from single-cell organisms into complex, space-conquering life forms.
