I'll toss in a few more I'm not seeing mentioned here over time. For now here's 1.
Love Esquire is a really good dating sim VN. Note it's not a pure visual novel, it is an actual dating sim hybrid VN with time management, map movement, stats, resources and a few mini games on top of having a lot of reading and choices. You play as a voiced Squire, and with an upcoming war you have a few things you want to accomplish before you march off to battle: You want to get some training in with your Knight partner, and you want to experience "Man's Greatest Pleasure". Your choices for girls are your farmgirl stepsis, two flavors of royalty, a brawler loli, and a shy pink haired nurse.
The general style and writing for the game is silly with lots of comedy, though drama and serious plot does kick in especially later in the routes for each girl. This is the sort of game where the MC's inner thoughts are often dirty and crude, like the MC will drop his pants and smack his butt to taunt enemies as a combat minigame move. There's a light general theme about growing up and getting serious within the game, but even near the end of routes the MC is still a bit of a goofball outside of scenes where he's risking his life or dealing with a girl's heavy drama.
The production quality is way above expectations for EVN. The art is really nice, it goes for some tropes like hiding the MC's eyes that might turn some people off but the girls all look great and the game has a nice variety in CGs (some of which are animated) and good UI art. The game sounds great with pleasant music and lots of English voicework too, the casting was well done and I think most people will recognize names like Kira Buckland and Amanda Lee in the main cast.
They handled H-scenes elegantly enough for Steam: the base game just fades to black, but you have 2 easily accessible options to add H-scenes. There's an official free DLC (Love Esquire - Greatest Pleasure) that adds H-scene CGs, and then a much improved mod available for free on the Steam Workshop (Hip To Be Squire) that adds extra story and animation to the H-scenes. The devs themselves recommend playing using Hip To Be Squire if you want H-scenes, so I'll have a 2nd link right to the Steam Workshop page for it.
