Yup, but that's what difficulty levels were designed for. Back in the day Normal was always a challenge to play, even for experienced players. Hard was for complete nutjobs and Easy was a challenge for less experienced players to play.
The change is partly down to publishers and testers, partly down to reviewers being shite at playing games and partly down to making Achievements and Trophies easy to get and complete.
The game industry has gone right downhill during the last 20 years or so, and not just the difficulty of games either. The design of games has also gone right down the toilet too due to developers and publishers not going anywhere near a designer that doesn't have a crappy design degree. It REALLY used to frustrate me when I was working in the industry. There were plenty of shite design decisions across a variety of areas of a game from level design to game mechanics. I lost count of the amount of times that bugs were entered into the bug database as design issues only to be closed 'By design' also known in the trade as 'Can't Fix, Won't Fix'
, and then of course you see reviewers bringing up these issues as problems during a review.
Used to drive me bloomin mental
You don't need a design degree to design games, if anything it gives you bad habits. All you need is PLENTY of game playing experience to know what works and what doesn't.
