We should consider ourselves lucky that anything but mobile games still exists, though I completely fail to understand why adults or rather people with access to credit cards play these mobile games.
Casuals outnumber hardcores by several factors. That's why content or even entire games targeted at hardcores never take off, while the mobile market makes unethical amounts of money. It's so simple, yet players never tire of acting like it's some unfathonable mythical secret of the cosmos.
