First of all, YES I KNOW IT WILL NEVER HAPPEN, I just want to know about what people think about it.
I imagine it to be Minecraft in somekind of random place you get to choose, (field, house or something like that.) you press a button and choose your elements. Then you play. You can make houses and stuff and then fill it with deuterium oxide and then pour neutrons into and and watch it EXPLODE!
Then ride SPNG around.
Just to make it clear, I KNOW THIS WILL NEVER HAPPEN.
