Even games like Cyberpunk, there were a very unequal content distribution between the option.
Hmm? CP77 had Panam as the romance option for straight male characters; River as the straight female PC romance; Kerry for gay males; Judy for lesbians. Aside from a few flings e.g. Meredith Stout that was it.
Unless you mean equal game time, then yeah; Panam and Judy did pretty well, River got, well, his own quest line, Kerry was very late game only, though the actual romance/post romance stuff for all characters was a bit threadbare IMHO.
