Ok but imagine your favorite game, I don't know what it is, maybe Dark Souls, Witcher, Zelda, or any other of the greats. You wait months for DLC which you paid for in advance and you get some random nonsense like Playmobil skins and levels. And everyone is like "hehe this is so cute and fun, games are meant to be fun, why aren't you having fun?!"
Forza fans perhaps expected to get motorcycles, or London, or number of other things that actually fit the game, but instead they got this...
If they made a Lego expansion for any of those (and sets to go with them) I'd buy all of it.
