Minecraft
Minecraft add-ons Flynn designed and built — both of them finished, playable, and running on Bedrock. Each one started with something vanilla was missing.
Chase tornadoes across Colorado in a storm-chasing vehicle you can ride. Get close and switch the radar on to read the storm, track it on the weather maps, and when the tornado alarm sounds, follow the twister — while every villager heads down to their basement. Nothing can hurt you out there; the whole point is to watch it.
Drive a garbage truck through Maplewood — a whole city generated from real map data, with proper streets, houses and businesses. Take a route off the dispatch board, work the neighbourhoods and the dumpsters out back of the shops, and watch your load, fuel and truck condition. Get back to the Municipal Waste Facility before the shift ends. Recycling and food waste are worth more than plain trash.
New addons go up here as they get built. If either of these sparks an idea of your own, take it and go and make it.
