do you any that are completed or recommend completed games if you don't mind me asking?
theres not a whole lot, but from what i can remember;
ones similar to this (regency style with more traditional romance, like balls and stuff) with mostly romance focus:
-The Ladys Choice
-the widow's boutique (on itch.io or mobile app)
-RegencyLove (mobile app for iphone)
-arcadie second born (generally historical with romance but not as heavily focused, and not as slice of life)
in general i'd look through this list for ones that look interesting, they're all released and historical https://itch.io/games/released/tag-historical
and theres not a lot on this site for regency stuff but if you ever check out choice of games, hearts choice, and hosted games (mobile apps but also on steam and online in general. theyre all tied together by their companies but function slightly differently), they have a good handful of regency or historical in general stuff. most of it is less focused on romance, balls, and suitors though.
You might like:
Scandal Notes - you play as a socialite in 1920s London, whose group of friends is being targeted by a Bridgerton style gossip column.
Oblivious Melodies - Regency inspired setting, you play as two siblings. This one is part of a series, and the 1st volume is completed along with the beginning of volume 2.
Affairs of the Court - you're pretty much playing as a fantasy version of Anne Boleyn (there's magic involved in this setting).
Crème de la Crème & Royal Affairs - setting is inspired by early 20th century & it takes place at a finishing school for socialites, nobles, & royalty (Royal Affairs has a royal MC).
If It Please The Court - you play as a court spy in 18th century Versailles, France. WLW romance only.
The Rose of Segunda & The Thorns of War (VN) - the MC travels to court for the Crown Prince's birthday & to compete to be chosen as his bride. The 1st game is completed but the 2nd is still ongoing, there are 4 routes done though.
Ambition: A Minuet in Power (VN) - you play as a woman trying to survive political turmoil in 18th Century Paris (during the French Revolution). It's also available on Steam & Nintendo Switch.
I also like The Lady's Choice (same author as Wayhaven Chronicles) and Regency Love that was already recommended too. They're both VNs.
