The review was written while the game was still in development.
the series is certainly a cult one, but lately Bethesda has not been happy, and part 6 will be on the Skyrim engine (although judging by the latest facts and bugs with Fallout 76, this is an improved engine from Morrowind) and this is not a plus, yes and the games live a long time mainly because of mods, well time will tell what the 6th part of the ancient scrolls will be =)
