Go play now some NES games. I never had a problem playing super mario bros 1 when I was a kid, went to my cousins house the other day. He still has his NES (not sure why) for his kids. I tried Mario 1 and was losing like crazy. So explain that.
There is a reason that the term "Nintendo Hard" exists.
But Super Mario never was a very complex game. in fact, most video games I remember from that time were very simple in terms of gameplay. This doesn't mean they were easy, as there is a difference between challenge and complexity, Morrowind is not the simplest game on the market, but once you familiarize yourself with its gameplay and develop a strong character, it gets pretty easy. A game can be very simple yet still be quite challenging, and while a complex game might drive away some players with its learning curve, once you've mastered it, it might still be extremely easy.
But it's understandable that Bethesda might choose to simplify the series. Like all game companies, Bethesda is a business, so they want to make money from their products. You could bring up things like art and putting out a quality product, and while that's all nice, if it doesn't make any money, it's still not going to allow a company to survive amidst competition with other companies that are making money. And besides, art and quality products don't mean anything if no one appreciates them, trying to widen a products appeal is a good way to allow it to bring in more money. It also may allow the product to reach a greater amount of people, thus allowing more people to appreciate it. One can only hope that in trying to increase the game's potential market, the developers don't end up alienating the demographic they've already managed to appeal to.
Regardless, though, Oblivion has already been highly successful, hopefully, Bethesda will take this as a sign that it needs not be simplified further.
Something people easily overlook is that simplifying thing does NOT automatically mean it's worse.
Now i'm not saying "the challange should be reduced" but you seriously have to think what SHOULD be made simpler and what shoul be made more of a challange? For example i doubt anyone would want opening DOORS to be more of a challange (and yes, having to manually pull or push doors open has actually been done in at least one game) but the same time it could be said that you have to be at least in arms reach to open a door or actually your characte having to reach out instead of seemingly opening doors with telekinesis.
On this I can agree, making something more complex does not always make it better, and simplifying it does not always make it worse. In fact, if something is unnecessarily complicated but adds nothing to the game, simplifying it would be an improvement, however, one could make an entire thread dedicated to the discussion of just what is
good complexity and what is
bad complexity. I do not wish to discuss it here.
