I agree with you. If a game feels complicated from the start, I usually don’t even give it a chance. There are too many options, so I just pick something easier. I read that modern mobile games focus more on quick understanding and simple mechanics, because that’s what most people expect now https://techadaptor.com/blog/why-quick-mobile-games-keep-fitting-the-way-people-use-their-phones/ . You open it, play for a bit, and leave. That kind of flow works better for everyday use than something that needs time and focus.

That's a really good observation. The context in which we use our phones is so different from how we engage with a PC or console. Mobile gaming is often about filling small gaps in time, so a game that respects that by being immediately accessible and enjoyable without a steep learning curve definitely resonates more. It's not necessarily about making games shallow, but about streamlining the introduction and core mechanics to fit the mobile user's typical interaction style.
