Tatooine is actually the first planet we encounter in Star Wars. Tatooine is where we meet Luke and Ben, and later on, Han and Chewie. It is also the place where we come across Jabba in Return of the Jedi. The place where Boba Fett is devoured in the Sarlac Pit. Oh wait (spoiler alert) no he wasn't. It is also the planet where we get to see Princess Leia dressed in that iconic gold bikini. Yeah, baby! Tatooine is also the place where those stormtroopers found those droids they were not looking for, and where the funny little Jawa race, make a living selling those same said droids and their ilk. Tatooine may have also held a pod race or two, but who really knows if that ever happened. Have I mentioned Princess Leia in that gold bikini? I have? Good.
As far as the planet itself goes, Tatooine, which was once teaming with lush flora and vast oceans (at least, that is what I am told), is mostly a desert these days (or at least a long time ago). It is full of lots of species, such as the Sand People (aka, Tuskan Raiders) who are the native and fierce nomadic race of the planet, the Hutts, who are just big ugly slug creature crime lords, and those aforementioned little Jawas. The planet also has two suns. Did I mention that? Yeah, two freakin' suns. Sure, other planets have more, but when you live on a planet with just one lousy sun, two is rather exciting. Anyhoo, let's just say that Tatooine, thanks to being the place from where Luke and Anakin hail, and where Han and Chewie first met the gang, is probably the most iconic place in the Star Wars Universe. So there! Star Wars wins. Two suns!!
