Harder, for perhaps unobvious reasons to most of you. Many of you only have a limited experience with the gaming world. I have played video games since the 1970's. To me a major aspect of difficulty has to do with the actual controller or number of commands that are available to the gamer. The original games had only a few buttons or commands that were accessible. Learning the commands for games in the early 1980's, for example, was pretty easy. A typical controller had Up-Down-Left-Right and maybe four or five buttons to access while playing the game. That was pretty much all you needed. Today, my mouse alone has 8 buttons and a scroll wheel. It has software that I can alter to make the game run smoother, making it harder to get just right. On top of that my keyboard can sometimes give me access to fifty or more keys. I have access to better weapons, equipment, and mods for just about every game. More choices in my opinion make the games harder.
In closing, I will say that there have always been hard games vs easy games. Memory limitations and controller limitations made some games harder back in the old days. The real time control of your character could be very frustrating because of equipment limitations. I still think overall todays games are harder (AND BETTER!), because of more choices, more memory, and higher equipment power.
