This is probably the oddest free thing to emerge from EA for the last few months: Tiberium Earth, which turns Google Earth into a kind of Tiberium-based fan mod. You get to imagine what it might be like if Earth really was infested with the crystalline super-resource from the games... Albeit using Google Sketchup, so not exactly click 'n spray.
I can cover your house in alien mess.
Which sort of begs the question of why anyone would want to? I don't know about you guys, but I'm a little surprised that anyone is investing much time in the C&C fiction. I mean - does anyone consider themselves a fan of the green stuff? (I'm imagining a conversation somewhere deep within EA where a dev playing with Google Earth explains what he's doing to his boss: "Sure, the kids love this stuff!")
