Off Topic but I finished my last exam today and I wanted to start watching Gundam. I wanted to know if you have any recommendations for which Gundam series I should start with first as someones who likes anime but has never watched Gundam.
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
If you want a super short intro to the series, _Gundam Thunderbolt_ is very good and self-contained. There's currently two hour-long OVAs that compile the first and second season. A third season and movie is planned, but it'll be a while before it's released.
It's definitely one of the more kiddie Gundam series, but it touches upon the themes of the original 1979 show, and is one of the few to depict the Stanford torus rather than O'Neill cylinders.
