Britain's most influential games journalist inspired me to go and review the Spore Creature Creator for Eurogamer. We'll be doing a RPS Verdict on it soon enough, I suspect, but I've already shot my critical wad here. I mainly think it's a miraculous piece of software, but spend a lot of time analysing the disenters' reservations with it: "In other words, while the Spore Creature Creator lets you play god, it doesn't let you be god." Fancy words ahoy, leavened with the usual nob gags.
EDIT: Since someone requested a creature, here's all three I screenshoted. Not exactly high art, but they're mine.
Lob 'em in your Creatures directory, and you're away.
