This at least is a bit more realistic than what’s being presented by Google. There are already a number of techniques for procedurally-generating a world (including Markov-based systems). The problem with replacing procedural world generation with LLM generation are a) you need to obtain a data set to train it, which doesn’t commercially exist, or train it yourself, b) there’s a fundamental need to iterate on the design, which LLMs do not cope with well at all, c) you need to somehow debug issues and fix them. That’s quite apart from the quality issues, cost and power usage.
