I could not get past the launcher at all at the time of release, but a week later (after the first patches) that was resolved. Have been playing it intensively for the past two weeks and have not experienced a single crash, even with other stuff running in the background.
A few days ago I managed to get robbed by a bunch of streetkids (I did not want to shoot them) so I lost all my money. And it's the best thing that has happened I now have to scrounge for every dollar and think before I spend it, which feels much more in line with the story. I found out by accident, but fishing with dynamite works a charm!
