I recommend the universal century, one year war movies to get you started: The mobile suit gundam movie trilogy followed by 0080: war in the pocket (a masterpiece of both storytelling and animation). In fact, starting with 0080 war in the pocket isn't a bad idea given the self contained story. From there, I'd check out 0083: Stardust memory and move on to the Zeta Gundam tv show. Then, for a completely different experience, you can check out the alternate universe shows like Mobile Fighter G Gundam or After War Report Gundam X
