Four pages and someone only mentioned Gundam once in passing! Give respect to the second greatest space opera.
Watch the movie version of the first series, then the the OVAs: War in the Pocket, and The 08th MS Team, if you're still on board, Zeta Gundam is next, but you'll want to pace yourself through that one.
If you liked the original series or any of the OVAs you can check-out the new ones they did, Unicorn, Hathaway and Origin, which is a prequel.
This is all Universal Century, to help you look it up.
There are a lot of Gundam shows that operate in different 'universes' but they all share themes, tropes, and giant robots. So depending on your tastes there's probably one might like.
