Dunno if I would call Eternum the pinnacle of AVNs, even if its without doubt one of the better ones of the current generation.
To add to the list:
Stormside and That new Teacher have both a lot of overlapping checkboxes with CC and have decent to good writing and animation. Stormside is on Hiatus for now tho, but has a good amound of content if i remember right.
Twisted Memories fits also great in, but has this whole bimbo thing going on in its aesthetic, that can throw off some people. And the last update is like nearly two years ago so get ready to be hurt.
I throw 30 days in too, but I havent looked into it for some time. Its more on the corruption side of things than anything.
Also, as always I put Lessons in love on recommendationlists for AVNs, because its probably the best and most uniquce thing the genre has produced, but its for once not for everyone and there is an debate if it is a porn game at all.
