The Player of Games by Iain M. BanksRead about another entry on the list.
A fantastic look at what a post-scarcity society might look like. There's no hunger, no disease, no war — just benevolent computers that take care of humanity and other beings. How could there be conflict or struggle in such a world? Well, Banks is a genius and spins one hell of a story about what happens when the Culture meets a spacefaring alien race with far less enlightened views. And it doesn't go how you think it would.
