What's so nice about MineCraft?
From my POV,all i see is very bad graphics,big pixels,building shit,weird looking cows,and very interesting models(pokeball etc) made by people.
so whats so fun
For me, it's the amount of customization possible. There are thousands of mods and multiplayer plugins that you can install and make that makes the game more interesting. And if you don't like the graphics, there's mods and texture packs for that. They even made a comupter mod where there's a mod that functioned like an old computer.
But really, it's because of the freedom you get, you can literally build whatever your imagination wants. Many different objectives to do in Minecraft, and with it being updated frequently with more items, tools, and monsters it just gets even better.
