This and pale carnation are the only porn game that are goated in my book
Eternum by Caridbis, Ripples by Jestur and Artemis by Digi_b are absolute BANGERS. The scenario is fucking amazing, I sometimes play it without even watching the seggs scenes. The story of the three games are truly amazing, and the animations are really really good. Can't pur more emphasis on this advice, you should definitely play those games!
I'd say it depends on what you're looking for. There are some really well done free ones out there like Eternum and Harem Hotel which are both still under development, and some completed ones like Once in a Lifetime.
While I take them less seriously, I've loved series like My New Family and Sisterly Lust which crack me up often (tho I'm unsure that's their intent). I admittedly stalled on the prior because it got to be a bit too much with its focus on the concept of incest, but it being a trauma dump simulator triggered a reflex for me to smile/laugh whenever sad music started playing. Mythic Manor had some pretty funny stuff too, tho I haven't played much of it.
I admittedly need to spend more time in different games like these since there's some genuinely good writing, but I also have a guilty pleasure for ones that are probably more on the "objectively bad" side of things just because of how funny some of the writing is.
