Know what sucks? Not being able to transfer save data.
When Grand Theft Auto V launched for the PlayStation 4 and Xbox One, it was with the understanding that players would be able to import save data and details from the PS3 and 360 versions.
Unfortunately, a serious bug prevented this from happening. If you hadn't played the last-gen versions during 2014, you wouldn't be able to access your old information for some reason. Thankfully, though, Rockstar has issued an emergency patch to deal with the problem, and they claim this has fixed the issue. It's currently available for both PS4 and Xbox One so make sure you download it ASAP.
Our review for the new version drops later today.
