"Mile wide and inch deep" is a great way to put it.
I'm playing through the game right now, and there's a bunch of small annoyances (like getting stuck on invisible terrain while walking/driving), but I can overlook those. But so many things are lifeless beyond the basic game mechanics.
As an example, I just bought an expensive apartment. I didn't expect a crazy cutscene or anything, but at least the person I bought it from should have shown some kind of reaction, maybe a short dialogue. But no, nothing. I pressed the button, money was subtracted, and I can enter the elevator. The person I bought it from didn't even look up.
Compare that to something like Baldurs Gate 3, where even small unlikely interactions have surprising amounts of interactivity. The game oozes life out of every pore.
It's depressing that this is the final state after so many updates.
Would you say the technology is developed far enough?
I'm definitely interested, as the phone screen size is often a bit too small. But any mechanical movement makes me nervous on a small device that should last multiple years.
