I think the best thing about Minecraft is that through stuff like modding, using resource/texture packs, and playing with fellow players if you can is that it serves as kinda a platform for other games.
For example, you can find tons of videos on JewTube about these guys playing these modpacks that make it actually quite challenging; such as this:

I have quite fond memories of the game, as I played it with a few friends I had back in those day: I also installed a fuck ton of modpacks and the like which added in a whole new fuck ton of things to do. I remember I played this mod called
Tale of Kingdoms which had RPG elements in it, and I also played this one called
Tekkit which added in a bunch of mechanical & magical stuff iirc.
