Clear out a large, flat area (use plains for less terraforming) and build a huge kingdom. I doubt you have a lack of wood, and you obviously have tons of cobble, so it shouldn't be hard- just time consuming. Make sure you have an epic castle (with a moat) and tons of buildings, ranging from workshops to inns.
First, build an iron lighthouse to the sky limit, with glass windows. Then, use your bricks and the remainder of your glass to build a huge brick mansion. Then, build a diamond statue, and maybe a small lapis one. Use your obsidian to build a large creeper-proof emergency room. Finally,use the redstone to build an elevator. It's possible that you don't have enough resources for these, though.
Iron Ingots: 4267
Gold Ingots: 155
Lapis Lazuli: 148
I use Buildcraft and Equivalent Exchange (1.0), With a 19200 cph(Cobble per hour) generator feeding a converter, Which can at any time be redirected for building resources.
So, What should I build? (I have a decent PC, So I'll video it to prove I build it legit)
I said legit, Never said it was vanilla legit :3
Helping raise Dragons
isn't a huge pain! Just
give 'em a click!
Flooded as in it keeps building up and I have nothing to do with it. Obviously I'm not rich, My 8 storey storage building isn't even half full!
Everything else can be as rail designations (like a Blue Line marked with the Lapis Lazuli, a Purple Lin marked with the Obsidian, etc.), decorations, or new stops for your rail system.
Either that or make a great, awesome kingdom and rule all of Minecraft.
