The world as it currently exists, in Minecraft, is rather drab in my opinion. Sure we have our fantastic mountains riddled with caves and such, but it all feels so monotone. Biomes don't feel genuinely unique from one another apart from some variance in surface features, and the underground portions are no different. Caves, as fun as they may be, have little to no variance between one another. A cave underneath one region will have the exact same stone in the walls as one twenty-thousand chunks away. Now that Minecraft has been officially "released" I believe it's time to whack out a few aesthetic details.
I, therefore; suggest a more advanced geological system than the current "dirt-stone-gravel" which our worlds are made of. These generic minerals could be replaced with more specific variations, such as limestone, granite, gabbro replacing our current stone; silt or loam replacing dirt; and et cetera. Metals, of course would need to be overhauled as well. Some new to the Minecraft world would be nice to see; tin, lead, cobalt. Also their respective ores; cassiterite, galena, and cobaltite may be a fun feature. They needn't a necessary purpose past being flavor or new building blocks.
Using fancy words like "cassiterite" or "gabbro" may not seem like the best idea. And it may seem as if they would frighten a newer player who is unfamiliar with them. How many other games, movies, or other media forms have you ever used and seen a term which you never once saw before? I would expect a lot of alien terms show up in daily life, and many of those terms you may have Googled or asked someone what they mean; and you, very likely, learned what that term means. There is also the chance you will then go on to use that new-found term elsewhere. The same could happen with these suggested geological terms. Players may not know what they mean at first. But surely enough, they will Google it, or search it on some type of wiki and learn a lot about what it means and how it's used. Minecraft would then be used as an educational tool as well as being an exceptionally fun outlet for your creativity.
Finally, the building. Haven't you ever wanted some variation in your stone walls, or maybe have a pattern of colored stones dotting the floor of your mansion's grand foyer, or have your house situated on top of a majestic white chalk cliff? Recent additions to Minecraft since 1.8 have been mainly adventuring geared, and while that is not necessarily a bad thing, the grand majority of players enjoy building. Creativity is the staple of Minecraft and the reason so many players were hooked on it in the first place. Adding new ores or minerals could open up a vast number of possibilities and further the development of Minecraft's creative outlet.
Summary or TL;DR
- Remove generic dirt, stone, gravel, sand, etc.
- Replace with specific rocks or sediments.
- More flavour.
- More building tools and blocks.
- Educational opportunity.
