So with the recent DDoS attacks, it looks like further steam integration is now high priority. So with this, I'm assuming we will get achievements sooner than later. So here's some ideas (given that the crafting path is still not quite defined yet) of possible achievements to add. These are definately not very clever so I need feedback. The more puns the better! Note that some of these also are similar or are movie or game titles so there may be copyright issues without further adjustments.
"Hot Stuff" - craft your first primitive furnace
"Botanist" - craft a sickle
"Iron Age" - craft your first anvil
"Bringin' Home The Bacon" - kill a pig for the first time.
"Grill Master" - craft your first grill (the black round one)
"Dungeon Decor" - die in a dungeon
"Rail Worker" - craft a train rail piece (I'm assuming these will be modular)
"Data Mining" = Mining silicon (if added) for the first time.
"Under Pressure" - Mining diamond (if added) for the first time
"Stone Cutter" - craft a block bench
"Heavy Metal" - craft a train
"Doctor Jones" - Discover your first dungeon.
"Crypt Raider" - First time opening a chest in a pyramid tomb.
"Maze Runner" - Open all the chests in a pyramid maze.
"Knee-Deep In Hellstone" - Mine hellstone for the first time
