The UC series takes a bit of time to watch, but I guess if you want a somewhat straight forward plot watch the classic, Zeta, then CCA.
Also Wing is best Gundam, but that new novel is a terrible official fan fiction.
Does anybody understands the whole series for Gundamn??
shits looks confusing/complicated and especially the timeline as well
I don't think they're related unless they share a similar name. It's more of a franchise if you think about it
