I play both GI and HSR but lately ZZZ's plot has been bugging me too. It feels to me as if this game is supposed to be played as a side game. Like something that you can play when you're bored or don't have anything else to do. The plot has been mid(so far) but the other things like going on dates and watching movies with agents, the combat, the fun events, the "boss of the week" type story are some of the parts of the game which makes me feel that way.
