I completely disagree about Quests. They're something new with regards to the Civilisation series. They're not new to games design in general but not much is "truly" new.
Aliens differ from Barbarians in a number of ways, of course they'll utilise similar scripts, but the premise is actually moderately different (spawn on Xenomass, Miasma synergy, variant Alien types, naval Aliens, etc).
The premise, compared to Barbarians, was substantially different. The failure was engaging with a range of players - however ironically the feedback from my Advanced Explorer mod is that people actually find aliens annoying or challenging and prefer the increased Strength my mods grants to Explorers. I've found more criticism about Aliens on this forum compared to any other venue, and in that regard people on here could stand to learn a bit about target demographics.
