Interestingly (well, for me anyway), I was recently working on a small side project with a similar premise to this.
I wrote short excerpts for a Minecraft diary writing both events and thoughts. The intention was to tweet one or two tweets per day.
The problem for me was that I didn't want to spam my Twitter followers with them ad I didn't want to start a whole new account based purely on MC diaries. So I had no audience in the end.
Anyway, here's the first bunch of days diaries to show you what I meant:
Day 1
Woke up in a large clearing surrounded by trees, cows and pigs. I have no memory of this place and I don't know how anything works.
I chopped down some trees and used them to craft planks and finish the half built shack I found.
At least I'll have a safe place to sleep tonight.
Day 2
Last night was so scary. A zombie type creature was wandering around the shack. His moaning and scratching on the front door kept me awake all night. I really need to craft a bed but I haven't got the resources yet.
Day 3.
Went exploring up at the local village. It's a nice place. Lots of buildings. Found chests with lots of goodies inside. I hope it was ok that I took whatever I could lay my hands on.
Day 4.
Nights are still a problem. A bunch of weird creatures wander around. The giant spiders I can whack with my stick but the skeletons fire arrows and are a real pain.
I spotted some kind of church on the horizon behind the clearing. I might go visit it tomorrow.
Day 5.
Some weird green cactus thing attacked me. I thought the creatures burned in the sunlight? Obviously not. I need to be more careful. The cactus blew up right outside the shack door. Spent the entire rest of the day fixing up the hole it left.
Day 6.
I decided to explore the village some more and found some good stuff. I feel as though I'm stealing so I tried my best to take only what I really needed. I prefer to craft things myself anyway so I can become more self sufficient.
Day 7.
SHIT! Got my arse handed to me by three cactus creatures. They blew up big chunks of a few buildings in the village. I don't have the stone and other materials so I'll repair them up as best I can using dirt. A bad day.
Day 8.
I explored the local area outside of the village. There's a farm with quite a few animals but excitingly I came across a mine that had coal! I can use it to craft torches meaning I explore deep exploring caves, mines and dungeons from now.
Day 9.
Over the last week and a bit I've learned a lot about crafting. I'm getting quite good at it. The only down side is that I don't have a lot of the materials required to make whatever I want. That church is still calling to me but I'm just too busy to go right now.
Day 10.
I
really need a bed. Night times are a nightmare. I got badly hurt by archers and zombies again. I don't have the materials to make shears so I've got no choice but to kill some sheep for their wool for a bed.
Day 11.
Well. I feel quite guilty about killing those sheep but having a bed is awesome! Best sleep I've had since I woke up here. I'm getting more confident with each day and am even going out mining at night. Long as I'm careful I should be OK.
Day 12.
Came across this cave with a beautiful underground waterfall. Spent ages just looking around. The night creatures are getting less scary as I'm getting stronger. I'm quite efficient at killing them since I made my metal sword. The archer's are still a problem though. Their arrows do a lot of damage.
So that was the idea. Be interesting to see what you come up with.
