Nope you didn’t miss anything if you watched all 24 episodes. It was just split into 12 episodes last fall and the 12 episodes we had in spring this year. Marketing called the spring run “season 2”. Typically a Gundam series is about 50 episodes split 24-25 each season.
WfM was only one season. They just broke it up calling it season one and two. Instead of being cour one and two like it was initially advertised as. And in my opinion the show really suffered from being only one season long. Hell just two or three more episodes might’ve done wonders. Show just turned into a pile of wasted potential in the end for me.
If you want another Gundam to watch I’d recommend giving Turn-A a shot. It’s only subbed though if dubbing matters.
Just gonna list a few.
Xenoblade Chronicles (1 & X): haven’t gotten around to the others yet.
Final Fantasy XIV & XVI: Soken is a god
Mass Effect
Legend of Dragoon
