> Factorio doesn't need that amount of RAM when it routinely handle dozen of thousands of items every tick. It might not inefficiently allocate all that RAM every tick, but it still has to scan a lot of RAM, and write to a bunch of locations to update the game state. It loves CPUs with huge caches because of that.
