I've got to say both as well. It's all well and good to say if you crank up the difficulty on certain modern games they're as hard if not harder than old games, but no, I disagree. Games have changed the focus of the challenge a lot, yes, and in some brief instances come close to the difficulty of the olden days. But Games used to be harder. It's true we as gamers have become a lot better at them, but trust me when I say games used to be a lot harder. As in tricks glitches and exploits were required to beat some games, and others were just thought to be impossible. I think the best comparison I've had has been Punchout.
One of my Nephews came over, and i fired up punchout for him. I ended up going through 3. The SNES one, the NES one, and the one for the Wii. On the Wii he got up to King Hippo pretty easily. SNES one he got maybe 2 fights down, and the NES one he struggled with Glass Joe.
It's easy to forget how hard these games were when we were little, and some of the extra modes and mechanics certainly makes the new punchout more interesting, but for whatever reason, controls timing whatever, The original seems harder.
Not all of our newer games have these comparisons to make, and a few series managed to continue to be incredibly difficult for a long time. But to all those Call of Duty fans, I ask, how many of them have beaten, from start, to finish, the likes of Wallenstein 3D, or Doom, or Duke Nukem. I played those games but never beat them.
That's not to say the current generation is inferior. Far from it. The crushing difficulty of games of the past turned a lot of people off to gaming. I think we're in a much better place now. We've got plenty of easier games, as well as some harder ones. We've got a good mix, and more of the games these days are a lot more fun. From shooting, to fighting, to action adventure games have improved a lot.
