Hi gang,One of the reasons I enjoy playing Minecraft so much isn't just redstone or the building, it's also the crafting and the involved "tech trees" as I call them. It's the same thing which got me hooked on the Command & Conquer series (and Starcraft) so much... Gather resources, build a starting point (base, or a crafting table & furnace within Minecraft) and expand from there.Of course Minecraft is totally different from C&C (or any other Real Time Strategy (RTS) game for that matter) but the tech trees are a bit comparable I think.For example; dig out clay balls and you can make choices. You can craft them back into clay blocks, cook those and you'll get hardened clay, which you can even use to apply colors on. OR you cook the balls individually which gives you bricks, then you can use those to make brick blocks and from those you can make other things like stairs and slabs again.And that got me thinking... What is the most versatile block of them all?My pick? Sand! Because sand can start so many tiers of crafting...First you have sand which you can smelt into glass blocks. And those blocks can then be crafted into panes. Not very spectacular eh?No, it's the 2nd branch which I'm interested in: sandstone.Sand can be crafted into sandstone. And sandstone can be crafted into stairs, slabs and smooth sandstone. And those slabs can be used to craft chiseled sandstone. Sand -> sandstone -> sandstone slab -> chiseled sandstone. So, any specific 'tech trees' which you like best?
