Japanese games very often have this - IIRC in Harvest Moon you even die if you don't get married i0 IIRC 3 yearse. Not to mention dating sims being mainly about this.

None of the old Natsume Harvest Moon games allowed same-sex marriage or romance. The more recent Story of Seasons games do: the Friends of Mineral Town remake (2019/2020) does, and pioneers of olive town does.

Both are more recent than the BioWare examples, and of course more recent than Stardew Valley, which is more in line with the Harvest Moon genre.
