Nostalgia and developers failing to fulfill huge expectations certainly play a huge roll.Nostalgia-based games seem to have not sold as well when releasing sequels. The shadowrun games as well as XCOM2 come to mind.
I think a lot of it has to do with tons of hype surrounding a game’s initial release, and then once fans realize you can’t recreate those old games, they just lose interest or are dissapointed.
X-Com is just not a very good example IMO, because X-Com 2 was outselling X-Com 1 in its first week. The sequel has tons of problems and a lackluster reception, which is probably why it didn't sell as well.
