My biggest achievement in Minecraft is actually learning how to sprint. In the first few days I didn't know how to sprint and it got spread around school. It is still viral.
3-4 years wondering why the hell i couldn't log on to any servers until i found out the difference between cracked and premium (my launcher was cracked 1.5.2) so my achievement was getting premium
Ugh.. Greatest achievement is.. Well my greatest achievement is buiding a modern house but after 5 months or 7 months maybe?.. , it got griefed but idunno why
Getting mad with EPearls and freely accessing the End in Semi. If MC achievements: Discovering all Biomes
Nothing. Im pro at all games. Just me being there and people seeing my nametag is an achievement for them.
Greatest achievement was in my single player game... Where I started off playing survival, mined a tonne of valuable items, then drowned while digging straight upwards. I got really moody about it over the next few days, only to realize I had cheat enabled and casually gave myself the items I lost. Then I realize minecraft actually had a creative mode and that I could build structures way easier in that mode ._.
