Honestly, I myself can’t think of one right now because the kind of games I usually play are more on the blockbuster side and those are mostly all about a straightforward narrative, action and stuff. But certainly there are some studious out there who tried to think outside the box and do something different with varying degrees of success by what I hear. One of such example I see people talking about is Hellblade curiously.
Look at the NEI page number for any decently popular pack, its usually 100-300 pages. Base minecraft takes up the first 3-5 of those pages. Modders are always going to be making way, way more stuff because they can do whatever they want, whereas Mojang knows any item they put in will be around forever.
