Take time to finish? And good? Not really... the only game that has "taken time" for me is Dating My Daughter... which if you're interested in development I suggest you play to learn what not to do. Dating my Daughter took most of the day when I first played it... I think... Been about 2 months...
Here is a list of games that have a couple hours of content each. None of them are gonna take time like a bigger project, but each of them are at least as long as a chapter or two of Life is Strange.
Coceter Chronicles has a couple hours of content, but we aren't talking about more than one or two sittings to finish up to the current version (I know that he just released the latest to his 20 dollar patrons though, so might wanna wait for the update.)
I Love Daddy is a relatively short VN, but it has 10 different endings, so playing them all out (which I recommend, because you won't fully understand the world until you do) will take a couple hours. However with the walktrhough and skipping past scenes you've already seen this time flies.
Big Brother, Man of the House, and most other Life Sims will also leave you playing for hours. However those will be hours of repetition and grind to get to a sex scene that is ultimately underwhelming after all the build up. Between the stairway to heaven, laziness, and bad art direction, they never end up as good as they could be.
Milfy City is in its 0.1, so far there are 4 characters (I think) with which you can advance the story, taking about half an hour to do each. If you earn yourself a bunch of money playing Rock Paper Scissors on your computer, you can buy all the items from the shops in about an hour of grind and you'll be able to play all the lines in about 2 hours. But as you can imagine 3 hours of gameplay in a game in its 0.1 is a lot.
View of Family, due to its having a similar format to MotH and BB, 2 sisters and mom, has plenty of content, so playing through each line is gonna take a little time. However VoF is much better written than the other two, so it has less grind. That said there is still some repetition.
Zoe's Temptations is complete, so therefore there's a couple hours of content, but its' one of the more playable games in my library.
Chloe18 also has a lot of content, since its recently finished, however a lot of that is the early stat grind needed to advance Chloe's own sluttiness, fitness, intelligence and Charm. After that its a matter of doing all the scenes. Still it is a fun game, gets quite outrageous at times. I suggest using the walkthrough to limit repetition and grind.
Good GIrl Gone Bad, being on its 13th release has more content than most games, each release covers about 2 days, so you have 26 days of game to play through.
Mythic Manor, like Milfy City is early in development, but it's possible to get each of the current characters to their first "sex scene" with the MC, so in going through each story you spend a lot of time.
