Playing the game with my mother after she bought it for my birthday back in 2011.
People touring the massive builds I worked on at nerd.nu i.e a 70x70 skyscraper extending from bedrock level to the height limit. This required over a million blocks be mined, processed and placed.
Getting various features to work in my ongoing mod pack that were jerry rigged together from seemingly unrelated mods. Eg. Modded overgrown stone from biomes o plenty that spreads and “dies” under the same conditions grass blocks do (The erosion 2 mod was used to do this)
The adventure and terror of not understanding how it all works when I first started playing. Mobs were scary, crafting recepies gave possibilities I didn’t know existed.
Minecraft before Microsoft bought it out and forced me to make a Microsoft account just to play it.
At some point, I had stopped playing Minecraft and I had an account since alpha but because of their account migrations where I hadn’t created a new username on the 2nd sign on system and the fact that so no longer had a receipt, I wasn’t able to recover my account. It was quite disappointing.
But I bought an account to play on Windows in bedrock because my son started playing and he wanted to play together with me. We still play and we could play for hours, just exploring and mining for stuff.
Building a cloud castle out of colored wool blocks in survival with my then girlfriend (now wife).
Playing in a world created by my boyfriend and his sons. We made a huge mine. I remember a cobblestone tower. Just in front of this was a small pool of water where I once died because of the bug that didn’t allow you to swim up while taking damage. We started with a small wood house and eventually made a castle out of smooth stone. It had a library and a kitchen and 4 beds - One for each player. I didn’t have an Xbox live account so when we played I was always logged in as a guest. Before leaving the game I’d remove all my armor and empty my inventory into a chest for the next time I joined.
