It's a shame that sales has a higher priority than quality these days.
That's the way it is for everyone these days. Every game company is more concerned about, "how little can we give them for the most price and biggest sales?" That was one reason they went against the trend of previous TES games and went for the Teen rating on Morrowind. They wanted a larger audience, and were willing to sacrifice a few long-time loyal customers for the gain of a few extra customers. Of course by the time Oblivion rolled around, they had the sense to realize that teens end up with mature games anyway, so why limit yourself to the restrictive ESRB teen rating. But they didn't go with Mature just because of the customers; they did it because they knew going for Teen wouldn't make enough extra sales to warrant all the demands they'd have to meet for that Teen rating.
And all games have gone the path of "easy" because gamers are no longer the small exclusive group that they used to be. A large part of that can probably be linked to the video game crash of 1983. Nintendo had to market themselves as a toy and a children's game in order to even get the companies in America to sell their products, there was so much distrust of the video game market at that time. And the games Nintendo released were much in keeping with that concept. The games were all very cartoonish and appropriate for all ages.
A whole new generation of kids was now playing games that were simple, addictive and fun, while the previous generation was still playing (and enjoying) games that had no hints, no walk-throughs, no HUD with pointers, and very few with difficulty settings. With trial-and-error games like "Out of This World" you were gonna die dozens upon dozens of times before you solved the puzzles and could proceed - no way around it. The challenge was enjoyable back then, but the successive generations got used to very simple games. Don't get me wrong, there were still many niche games and difficult games, and as difficulty settings became the norm, people could have their fill of anything from easy to insane - whatever they wanted. But the hardcoe gamers were a minority, and targeting a minority group for sales is just a bad business move.
I don't always like it, but I have to agree that the companies do need to follow certain patterns to make sales, especially as game-development costs continue to skyrocket. You aren't dealing with games that take a few weeks and a handful of people to design anymore. Games are becoming like movies now, with dozens and even hundreds of people involved in the process from start to finish, astronomical development costs, and years of production. It's just too dangerous of a business model to take risks with such huge investments riding on the line.
Like I said, I don't always like the results of that, but in this age of games, that's just what we have to accept. Most companies do try to play a balancing act of meeting as much of the wishes of as many of their customers as possible, but in the end they are going to have to make compromises. And as everybody knows, the simple fact of the matter is that you can't please all of the people all of the time.
