SOLUTION: PLANET OF BLOCKSANSWER: MINECRAFT WIKI
This puzzle presents solvers with a large grid of items from the game Minecraft, with a series of numbers along the last row, and a list of other Minecraft items below the grid. As hinted at by the flavortext, all of the items in the list at the bottom can be crafted in a 3x3 crafting table, where other items are placed in specific arrangements to craft them. Each item's crafting recipe appears exactly once in the grid (only allowing for horizontal reflection). Here is the grid, with an overlay of black lines denoting each crafting recipe:
Each column of the grid has one item which is not part of any of the crafting recipes (circled in green in the above image). The number at the bottom of that column can be used to index into the item's name. Doing so produces this puzzle's answer, MINECRAFT WIKI (a resource I expect many solvers will have used extensively over the course of solving the puzzle).
This is pretty much the most basic form that I think a Minecraft crafting puzzle could take. For a difficult and way cooler take on this concept, check out the puzzles Crafty Clouds and Masters of the Craft from this year's Teammate Hunt. My only hope with this puzzle is that at least one team got to have fun shouting "FLINT AND STEEL!" at each other over a voice call.
