Really enjoyed it. Perfectly captured the feel of the Fallout games (the Bethesda/Obsidian ones, don't know the first two). And yes, there are a lot of elements from the games they can still use for future seasons. Locations, factions, monsters and, hell, maybe even characters, despite the timeframe.
Supermutants, Deathclaws, Synths, certain types of bots etc.
