A week with Spore Creature Creator: Day One

Personally I think that your main problem is believing that basic biology applies to this title. For example, the creature you provided, who's to say that the upper bulbous portion isn't filled with helium or somehow floats and all it needs is a little foot to drag it around? Or perhaps it can propel itself some other way and uses the foot to steer?
Spore isn't supposed to be realistic, it's supposed to be a game with a really powerful editor that can let you make some amazing creatures, physics be damned.

The point of Spore is that you can create anything you want without the game telling you you're wrong.

Imagine if you finally picked out all the parts and colors for your creature only to find it flop around on the ground.

Yeah I know... where are the physics? Didn't all the demos they showed us pride themselves on the physics (Robin William's creature sagged with weight, lol... I wouldn't care if my creatures sagged a ton because they defied gravity so much, better than randomly floating). Maybe it's just in the real game the physics will be back. I sorta like the challenge of making a balanced creature, both functionally and physically.

Au contraire, it is quite possible. Smaller planet with lower gravity, air bladders filled with helium produced as a byproduct of diet, antigravity appendix... the list goes on! The appendix is stretching it, but I couldn't resist the alliteration.

Clipping limbs? Gelatinous.

Possibly but BB received no hype in comparison to Spore. Maybe Spore'll end up like GTA 4 and Halo 3 though where people begin to realise there are faults after the hype dies down a bit.

Then you obviously forget this is made by the famous Will Wright, creator of The Sims, one of the most famous games in the industry. This isn't a movie maker trying to put a spin on games.

NSFW warning pl0x!

Spoiler: the link has a Spore penis creature.

Generally no, you won't get a discount on the full game I don't believe.

But right now Amazon is giving $5 towards a future purchase of the full game. So this makes the creator only $5 instead of $10 if you buy both from them.
