Why chose a Themepark game design

Because WoW made tons of money.

Well this is depressing as fuck. I am going to bed.

...

Because being a solo autist is what it's all about now, user. Don't you want to be like that dark trench coat wearing dual wielding edge master in that one chinese cartoon?

This is a big part of it. Games these days are at the mercy of the investors and shareholders WHO DO NOT PLAY GAMES and us devs have zero freedom when all they care about is the returns except when they think they know better than devs and players, which is usually. They have no creativity whatsoever and only care about copying what the most successful models in the industry are doing like WoW and this is a huge reason why there are so many WoW clones. We can't even make a game that isn't one because we're not allowed too and investors in the game industry seem to hate risk unlike other industries. Oh and they're a bunch of cucks. HUGE HUGE cucks. They have no idea how badly this hurts either because it alienates so much of potential customers.

Don't kid yourself. All entertainment industries hate risk. This is why we see so many formulaic "summer blockbuster" movies or why Blockbuster laughed at Netflix when the latter offered to sell itself to Blockbuster in its early days. Books, too. I'll bet there's at least a hundred publishing firms still flogging themselves for telling JK Rowling that they didn't think Harry Potter would sell.

I don't know how to feel about this

No?
Fuck that. I play mmos to grind and to forget about the real world. If I wanted interaction with other fleshbags I'd go outside.
Major problems in modern MMOs are shit combat and pay2win models.

don't forget the stupid dad smart woman sitcom formula that has been around since before the fucking 60s
