I'm so tired of open world games taking forever to beat, and every mission just waits for you to show up. It feels so artificial. But now if you have a limited time to do everything before destruction happens... that's cool!
I think they should take it a step further. Add an in-game clock where specific missions happen at certain times, and to access them you have to be in the right spot at the right time. Otherwise, the mission already starts without you and you missed it. And even when you open the pause menu, the clock keeps ticking.
