The fact that you can list four female characters in the 80s and 90s is by no means equivalent to the notion that "there's no shortage."
Do we really need to go there? You can use google as well as I can.

...oh, look. Others have already done this:
Here's a list of
26 PAGES of games with female protagonistsIf you really think there's a "shortage" of female protagonists in games, you're not looking very hard.
Actually this is a VERY important example because it shows exactly why there is an issue with women in videogames. Chun-Li by all means is the female protagonist of Street Fighter, if ANY woman can claim "main character" it would be her.
Plenty of the games in the above list feature women definitely in the role of main character. Lara Croft and Samus Aran being especially well known examples who each have an entire series of games about them...but even as far back as 1987 we had characters like Alis Landale who was a sole female protagonist who picked up a guy, a cat and a person of uncertain gender to play sidekick for her while she went off to save the solar system.
I remember playing these games as a kid. Doesn't anyone else?
This whole thing seems like a
Dead Unicorn Trope to me. There have been games with exclusively female protagonists pretty much since games originally evolved to the point of having defined characters in the first place. How far back do you want to go? Pac-man? There was a
Ms. Pac-man too. That was in 1982.
You cannot claim that there's ever been any kind of shortage of primary main-character female protagonists in games and maintain any kind of credibility.
