Everyone who was unwilling or unable to play Minecraft 1.8 early can now get the update without having to manually substitute files. With this significant "Adventure Update" behind us, now is as good of time as any to get into the game, even if you're going in blind.
My favorite additions are the towns and mine shafts, though there is plenty to be excited about here. I haven't heard what the general reaction to the new features is like yet. You guys are silent because you've been playing this entire time, haven't you? I knew it.
