There are quite a few other English games with these same elements, though they aren’t as prominent in other titles.
The best example of an English language dating sim was the PS1 game Thousand Arms, released by Atlus.
It was a fairly standard RPG, except to forge stronger and better weapons, you’d have to go on dates with, and raise the affections of, the female characters in your party.
But those aren’t the only kind of dating sim style games in Japan.
In fact, there are likely far more dating sims geared towards guys available than there are ones for girls.
