Having completed it (short game!) I retract my impression of their engine. When you see everything active at once it is very good.
Really needs a proper game though. This feels like a tech demo contrived into a game, with a number of 'unfinished' aspects. For one you can zoom in on a person and you're told something about them, which is always "This (wo)man can build villages, carry knowledge, and something." Why have that if there's no need to identify different people? There's mention of a creature I never encountered. And then the last level is just a tech showcase. It's as if Ubisoft had no faith that a god-game would be financially viable any more, and told Chachi to get 'something' out there quick and cheap to prove his tech wasn't a waste of money.
This tech with the gameplay of something like Populous or Megalomania, where you have to build villages and grow your population fighting against various elements. Some Settlers style resource harvesting wouldn't go amiss either. It would be an awesome game - I fear it'll never get made.
Really, what we need is for Molyneuz to stop faffing about with his 'new wave' game ideas and get back to making God games around the capabilites of modern hardware!
