I can understand this, even if I don’t agree. I guess I just really enjoy stories, and I love “owning” part of those stories. I love Bionicle because of its vast, amazing, and interesting story that never gets old. Because of this, I want to “own” a part of that story. I never really felt Nexo Knights’ story, I wasn’t the target demographic anyways.
I love Overwatch because of vast characters and abilities. On top of how much fun I have in the game, I also love the lore, and learning about my favorite characters is awesome. And so, I was very elated when I heard the news of LEGO Overwatch. Despite the lacking of my favorite character in any of the sets, I will be buying Reinhardt and D.Va because I like those stories and I love to play the latter.
At the end of the day, I’d rather have a Hulkbuster set on my shelf than a Knight Mech, simply because I know and love the story behind it. I like the Harry Potter sets, but, because I don’t like Harry Potter all too much, I won’t be buying any. Besides, I have a few highlights from the last wave (if I didn’t already have the Knight Bus, I’d probably buy it if they made another).
