Currently waiting for the 'Kindres Spirtis on the Roof' game, but even this released it will be not nearly enought girls kissing each other around me. Fire Emblem also look nice, but, alas, there is only one bisexual girl there to smudge with. At first I've thought I could turn my army into lesbos paradise.
So here's the deal: we gonna share each other good quility games with good quality girl+girl relationships in it, thus forever coloring this world pink. Whaddaya say?
My favorite games:
1. Eternal Felina.
This one takes the cake. Classic 16bit console RPG at it's best but... with female gay marriages. Well, not actual marriege, since our heroine is reverse trap and her love interest is a lady of pleasure, but still. Good combat system, inresting fairytale plot, good visuals, solid RPG experince makes perfect with some yuri themes makes this game perfect.
2. Summon Night: Swordcraft Story 1 and 2.
If you gonna play as a girl and gonna get yourself a right summon at the very start of the game you gonna have a lot of funny dialogs. In the first game it's an elf named Suger, that gonna proclaim herself as your lesbian waifu at instant. At the second game it's an imp girl. Not to many lesbian scenes with her, but many other girls gonna pick interest in the female heroine.
3rd game currently in translation here https://gbatemp.net/threads/summon-night-swordcraft-story-beginnings-stone.389972/
3. Zone of the Enders: Fist of Mars
Phil is does not look like trap, he is a girl. It was intentional mistranslation to make the game more dull without any selfish love from one gal to another, that never going to flourish. Even so, her selfless feelings will be cherished by us all, cause know we all know that Phil is a girl.
4. Fear Effect 2
Not much relations development here, but many hints and clues about that two heroines more than just a co-workers. Game arts can overcompensate for this tho.
There is Bioware games, but everybody should know about them by now.
There is also DLC for last of us and Life is strange game, but lesbians there are so dull that I haven't got a single boner. But the games are as boring if you ask me.
I've also heard that about some Harvest Moon games having same-sex marriages, but even those had em was ridded of em during translation.
