Taking full advantage of sexy ray-tracing tech, the map adds in some fun Christmas-themed storytelling, from an interactive Santa in his grotto to rides, food stands and even some make-shift quests. It’s a pretty impressive creation, taking one (probably exhausted) Minecraft specialist over 3000 hours to build and spanning an absolutely mega 38 acres. In a clever touch, the free map allows users to donate to the hospital using in-game mechanics, with a full recreation of the hospital nestled into the Noelle diorama. For those who are unaware of the brilliant work that GOSH does, donations will help fund the hospital’s medical technology, research for cures and treatments of rare conditions and bolster patient and family support services. In other words, it’s very much money well spent. It’s been a pretty good week and a bit for Minecraft, with Mojang’s unstoppable blockhemoth racking up over a trillion views on YouTube. It’s somewhat unsurprising then that NVIDIA would still want to use Mojang’s beloved creation in order to reach such a mammoth audience.
