What’s the longest otome / BL game you’ve ever played?

Slow damage. It was my first VN, and it took almost 80h

Hana Awase would be the longest one; the reason it felt so long is that it consists of four volumes—or rather, four different stories: Mizuchi-hen, Himeutsugi-hen, Karakurenai/Utsutsu-hen, and Iroha-hen (with Iroha-hen being the longest). Each title is split into four fairly long games featuring five routes each—not to mention the "jealousy" mini-routes involving other guys if you choose one of them while on the current character's route. Among the four, I'd say Iroha-hen was the longest, though I didn't like it enough to finish it properly; I ended up skipping through it after playing for several days, only to realize there was still more story left. That would definitely be the longest game I've played.

Tokimeki Memorial Girl's Side 1 for me... I'm trying to get all endings and all CGs. Each game has so many routes/characters, and the Buddy endings are quite finicky to get. The stat raising can also be tedious and unpredictable.

Also it took me ages to realise you can speed up the activities in the settings!!!!!!! I would've saved so much time!!!

it takes me pretty decent averaged to finish an unlocalized blvn so ooe so far has taken me a while. otome wise im unsure cus i do kinda take my sweet time lol thats how i hit over 100 hours on dialovers more blood

The longest otome for me would be the obey me franchise it's been so long forgot when I started but I played everyday trying get some my favorite characters cards reading lore it was fun but lost interest years later was going to revisit but game got into bit controversy (ToT)

What I played was Ken ga Kimi, including the main story plus the FD afterstory. Because I played it on PS Vita back then, I had to struggle through it in Japanese, and for overly complicated words I could only rely on taking photos and translating them, so I spent a very long time playing it.
