The reason Valve never persisted and saw Half-Life 3 through was because the Source 2 engine wasn’t finished and development was unworkable without it. One of those was formally meant to be Half-Life 3. For instance, at least five Half-Life projects were started and then scrapped between Half-Life 2: Episode 2 and Alyx.
