Please suggest some Gundam-like shows to watch

Hi all, I came back to anime after a long hiatus thanks to Witch from Mercury.

Since then, I’ve watched a bunch of anime - including many masterpieces - but nothing could scratch that itch like a Gundam series could.

So now I’m look for more Gundam shows to watch.

It doesn’t have to be Gundam exactly (or even anime!). As long as it shares the main features, I would consider it to be Gundam.

From what I observed, the following themes are essential to Gundam series:

War - To be specific, it shows how war is bad, and that nobody truly wins in a war.

Child soldiers - Usually forced to fight, or manipulated into fighting (by people who would usually get revealed to be the real villains later).

Politics - What started the war, or kept the war going. The politicians tend to be the ones manipulating others.

Tragedy - In war, people are obviously going to die. Personally I would prefer if the main cast gets a happy ending though.

Discrimination - It can be discrimination over race, class, etc.

“Mecha” - I am using the term mecha loosely here, because it doesn’t really have to be a robot that’s piloted. It can simply be some kind of enhancement or weapon of war, or something symbolic; usually a game-changer in the war.

Other themes that I have noticed are common but not really essential include:

romance subplot - Looks like in war, love gives people hope, as well as the drive to keep on living.

dystopian setting - It could be the lasting effect of previous wars, or the consequences of politics.

Finally, these are not really themes, but I’ve noticed these trends:

the protagonist tends to not fit in with their society
there’s usually an ensemble cast; would likely be the protagonist’s found family
the protagonist’s team tend to switch sides in the later stage of the show to fight against the true villains; usually resulting in a three-way conflict
the mechas would progressively get upgraded over the course of the show
usage of WMD (e.g. a giant laser beam)
there’s someone - usually a villain - whose face is hidden, usually with a mask; tend to have a grandiose plan (i.e. Char clone)
there’s a princess character who may have some level of influence or authority over the others, or is otherwise special in some way; tend to serve as the love interest of the protagonist; hair color usually stands out from the rest of the cast

To avoid overlaps, here are the Gundam-like series that I have watched / plan to watch.
