I think trying the experiment with the knowledge of this one would be interesting, Would more people hoard materials early as the griefers did? Or would people work together?
It reminds me of skyblock, the map with one tree, some dirt, one lava and two water blocks and a chest of seeds.
From my old-skool minecraft knowledge;
1: Logs, Wood, Cobble and Stone are all renewable building materials. (One sapling can turn to infinite logs and wood, and one bucket of lava and one of water is infinite cobble.)
2: Grass can not be brought back once destroyed, but will spread infinitely over dirt.
3: Mushrooms can be grown without grass but need wood to become food.
4: Torches can be made with charcoal. Only trees are needed for light.
5: Leather, stone and wood gives you renewable armour and tools.
5b: However You can only mine diamond with iron and can only mine obsidian with diamond
6: Animals can spawn infinitely as long as you have grass and Monsters spawn infinitely in the dark(Though I heard talk about this changing to some breed system, that seems unlikely as then how do monsters work at night? do they go to caves?)
7: disregard this out of date information, after all the game is still in beta and will have changed a lot... right?
