The carebear vs. hardcore gamer issue with gaming was always a problem and especially in the MMORPG space before women.

What WoW did was prove the carebear model was more profitable and thus all gaming companies and especially MMOs chased the carebear model. This didn't ruin gaming so much as it ruined MMORPGs but frankly, MMORPGs were dying out anyway before WoW because the nature of hardcore gamers is that they don't like to play if someone else has an advantage and they don't like to play if they can't gain an advantage over someone else, so after any initial game launch, a group would gain an advantage such that everyone else (even if they were a hardcore gamer) would quit the game, then the server pop would decrease and the company would pull the plug.

Outside of MMORPGs, there's a lot of different reasons for the destruction of games. I was a pro CS 1.1-1.3 player and I could go on for hours about how and why FPS games were ruined... but instead I'll focus on single-player RPG games.

The issue truly does come down to hiring female developers. The reason is because of the difference in the nature between men and women. When men do fantasy, they create characters that they want to be like as the primary motivation and then they make these characters somewhat like them as the secondary motivation. A nerdy guy who can't get girls makes a hot dude with a harem but has qualities somewhat like himself (the dude is smart and isn't a brute). When women do fantasy, they create characters like themselves as a primary then make the characters somewhat like what they want to be like. So when you hire ugly adversarial feminist lesbians to program you fantasy games, what do you get? You get ugly adversarial feminist lesbians as the main character who also save the world (but as the secondary). This completely ruined gaming for men, yet it didn't necessarily help expand the target demographic because not every woman out there is an ugly adversarial feminist lesbian but when you hire these women to make your games, they will make the games about themselves rather than make the games in a manner that truly expands the target demographic BUT at the MBA meetings, the women will lie and say they believe this will expand the target demographics. The useless boomer executes/investors don't understand how things work and it sounds plausible so they go with it. The result actually has been the destruction of the video gaming market without the boomers or feminists either having a clue why.

A bunch of White men who understood things and wanted to expand the target demographic could still make video games that both men and women enjoyed without the bias that female developers would have on how they were making the games.
