Has anyone been following this game at all? I heard about it from a friend the other day and spent some time looking into it. Let me just say, it's amazing. It's another stroke of genius from Will Wright (Sims, et al). Basically, this time around, the name of the game is almost, if not, TOTAL personalization, plus easy sharing between all players.
The concept at the base of the game seems relatively simple, although it spans multiple levels. You start at the cellular level, fighting for survival, then go on to the creature level where you get to build a creature and interact with other species and creatures. From there, onto the tribal level where you begin to organize with others of your species into a small society. Then it's into city mode, where cities begin being built. After that, the game is taken to space mode where you can leave your planet and explore your star system, and even the galaxy which is made up of MILLIONS of star systems.
In terms of release date, it's looking to be around Q1 of 2007, and I must say that it's caught me. I just hope this game doesn't collapse under its own weight like other novel ideas have before it (ie, The Movies, in my opinion).
