Looking for good game theory recommendations.

I did an undergrad in physics with a minor in math so I have a semi-sophisticated math background, but I don't know anything about game theory. Lately I've been reading a bit about evolutionary biology and economics, and game theory comes up in both. I'd like a good beginner text to go through in order to learn about game theory. It would be great if the examples pertained to biology or economics as well.

Also ideally something not too dry. I'm smoothbrained and enjoy colours and pictures over long boring passages. For example I hated Dummit & Foot, but really liked Gallian's abstract algebra text.

Thanks.
