An incredible concept indeed, i could hardly believe it when i first heard it.
Well actually, some stuff he said i do not believe, or at least, until i see it with my own eyes.
1. Walking pattern of creatures is recognized by the software, not pre-scripted : I am truly sorry, but has it not been proven that Pre-Script are easier and cheaper to do than having an "engine" that will adapt itself to any custom form the player could give to a creature? Seing how Wrights describe the way they produced that "Recognition", they said it's even smaller and easier.
2. Seing most if it's Sim-Games, i know that they are usually way editable, but will Spore be really THAT MUCH customizable?
3. This is turning into an Multi Mass Online Multiplayer Game, i don't see how they will prevent ruining the fun, except by making the whole game offline, with just downloadable custom content to add to your own universe.
4. While the concept is really insane, and makes me salivate just reading about it, a big lack of all wrights game has always been "No actual goal, objective, or ending". You may think the no goal effect is pretty cool, i do also say so myself, but you while bore, everyone will. Most people already did with SimCity. It's good, but has no actual reason to be played.
Don't get me wrong by my statements. I am a big fan of all Will works. I'm a huge fan of SimCity and most other Sim variations, but i do ask myself questions about the possibilities of such a great game to birth in our era.
