This is the initial manga version of Mobile Suit Gundam, published while the TV show was airing. It should not be mistaken for the 1994 adaptation titled Mobile Suit Gundam 0079 by Kazuhisa Kondo.
Not meaning to offend you but how? It's heavily focused on not too big of a cast and the main plot gets brought up periodically, last time being in this chapter. But I will say that having reread the series recently, it made me appreciate a lot of the foreshadowings and small hints thrown in the story that lead to a bigger picture.
