No Man's Sky (2016)

Hello Games' No Man's Sky (2016) launched with only 21 of the 42 features promised in pre-release demos, triggering 200,000 refund requests within the first month. While Fire Phone's price collapsed within months, No Man's Sky held its value initially but garnered a Metacritic user score of 2.8, compared to the average AAA game score of 7.0. The game ultimately improved through patches, but its launch remains a benchmark for overpromising.
