I know this is a big favor to ask, but I've been thinking about watching everything Gundam.
I've been thinking about watching the compilation movies when possible, but I've heard that there are many of them are pretty bad.
Could someone give me a list and order of series/movies that I should watch?
So far I've seen the whole 00 w/ movie and 6 episodes of Unicorn.
I'm a big fan of production order, but I know it isn't for everyone.
If you want to get into UC timeline, starting with First Gundam is a must. I prefer the TV series, but the movies are good and have their own strengths (such as a better finale in movie three due to an awesome song that is movie only).
From there, you have Zeta Gundam. There is a compilation movie trilogy called a New Translation, but it isn't very good and cuts out WAY too many key moments and doesn't make sense.
After that is ZZ Gundam, which is only a television show.
Then you have Char's Counterattack, which is a movie.
You've already seen all available episodes of Unicorn. That takes place 3 years after CCA.
From there, you have the OVAs. There is 0080 and 0083, which take place during the first series and 3 years after the first series respectively.
Then there is 08th MS team, another OVA that takes place during First's time.
After all those are done, you have the "Late UC" shows. There is F91, a movie that takes place 30 years after Char's Counterattack. And then there is Victory Gundam, a series that takes place 30 years after F91. Neither really are that closely tied to each other or the other UC shows.
After that, there are the AU (alternate universes). The first AU is G Gundam, a TV series. Then there is Wing Gundam and it's follow up OVA, Endless Waltz (there is a re-edited version of the OVA, which is essentially the same but with a few changed scenes). Then there is Gundam X, the only Gundam series besides the original to be cancelled.
After all of those are watched, I recommend Turn A Gundam. For me, this is kind of the conclusion of "Classic Gundam". It's a nice wrap up of the franchise from 1979 - 1999. They could have ended the franchise there and it would have been nice. There are (two?) movies that are compilation films, but they're bad so don't watch them.
Instead they "rebooted" the franchise with Gundam Seed, which is popular but I don't like it. It had a follow up series called Gundam Seed Destiny. There is also an OVA that is set in the series called "Stargazer", which is actually pretty damn good IMHO.
You've already seen 00 and it's movie.
After 00, there was Gundam AGE, a tv series broken into 3 generations. It had an (OVA/Movie?) called Memory of Eden, which added some new material to the middle arc of the story. Frankly, I hear the PSP game by Level 5 is the definitive version of the story though (Level 5 had a huge hand in developing the show, so it's almost like the show was a tie in for the game, rather than vice versa).
The current running series is Gundam Build Fighters. I hear it's supposed to be about 25 episodes. It's pretty good IMHO.
There is also an OVA called Gundam Igloo, and Gundam Igloo 2. Igloo focuses on Zeon Engineers, while Igloo 2 focuses on grunt soldiers and some hogwash about death gods.
There is also one final OVA called Gunpla Builders, which I recommend watching before Gundam Build Fighters since it is only 45 minutes long and is essentially the same concept as GBF
