*has been playing WAY too much Technic pack*
I'm farming mushrooms to get diamonds so I can build energy collectors so I can transmute light into iron so I can build Generators to craft into Solar Panels so I can build Solar Arrays so I have enough power to run the Rotary Macerator I'll create from Advanced Machine Blocks so I can get maximum dust from my ores so I can have enough materials to build a Geothermal Generator with a Teleport Pipe above the basalt volcano near my house so I'll have UNLIMITED POWAH!!111!1!! so I can build advanced machinery to mine out all the goodies in the area before the blasted Taint gets into the tunnels and eats it all.

Once I have enough of those goodies, I'll be able to construct crazy stuffs in order to make Totems of Dawn so I can knock back said Taint. THEN I'll be able to start just "playing around" with stuff.

Oh, blast, I've forgotten to loot that chest from the conquered dungeon for three full real-world days now. I'd better stow my gear and go down to get it...
