There are plenty of games where time doesn't matter.
"Help my wife is poisoned and is going to die! " you could wait 100 hours of real time and she still wouldn't be dead. Or she should already be dead if you didn't visit him the first time soon enough.
And there is a trade off as has been said. You'd get people who would have to rely on guides to metagame and such. Need their hand held for lack of a better word.
That is, in my estimation, the least of it. BG2 did the same, as I pointed out in my post. The important thing is that *you* were still anchored in world time, only the event would wait. So when you traveled, a sense of time and distance was maintained. I am not against events waiting for you. At least, that's the minor dissonance. It is sometimes a necessary compromise, easy to adapt to. I am against being unmoored in time and the trivialization of distance.
