I kind of miss game overs taking you back to the title screen and limited save options. Now there's too many checkpoints and death isn't a punishment more than an inconvieance. Now when gamers get stuck at a point they just ram their head into the wall brute force rather than focus on their mistakes, because the stakes are low.
The problem with the old system is losing progress due to external factors like power outages, or a brain fart because you forgot to save the game after 4 hours of progress.
