My first time MC (back in early beta, 0.5 xD), I played on a server hosted by a friend of mine and I knew all of the guys there in RL, my only problem was that they started playing long before me and knew the stuff already, and everyone thought someone else had shown me what to do already lol (it took me three hours there to get someone to tell me you have to use tools to make stone and ores drop stuff when you destroy them)
I built a treehouse in a forest near the place a friend of mine had a wooden villa, and dug a hole into the ground below, found some ores, built a furnace, as it goes (back then, MC was only crafting and getting resources, no strongholds and only 3 biomes. we didn't even have beds lol we went mining at night because there were an equal amount of monsters in the caves and on the surface then xD)
but I had no idea how to use a furnace, so I tried to light it with flint and steel. in my wooden treehouse. in the middle of the forest. my friends wooden villa near. back in beta where fire could spread infinitely.
it was quite impressive, there was a hill nearby, all of my friends gathered there and we looked at the inferno that roared from down at our feet to some point far beyond the max render distance, engulfing some really great buildings that stood there, getting an idea how emperor nero must have felt after setting fire to Rome xD
after it all burnt down, only ashes left, the host restarted the server with a backup from half an hour ago lol
