Idk, i'm still more likely to want a play a snes game when I get bored then any gamecube games, but I might be biased, as I'm not sure, but I might be half retro. (thats a thing now)
Games might be getting better graphics, but that doesn't make them superior, at the end of the evening what was more important was how much fun/ enjoyment the game gave you, and are you willing to replay the game.
Now for 3d, like Elderscrolls, i've tried, i've really tried to enjoy the ones before skyrim, and yet i can't bring myself more then a few hours in, yet with skyrim, I've played that game like 10 times, counting just making characters to run thru side faction quests only, twice the main quest. And I'll admit for that type of game, the graphics really do make it more immerse and fun, and the fact that guards aren't mad at me for accidently trying to open a locked door and deciding not to pick the lock with no witnesses, or stealing my own horse.
For like say star fighter style games, man back in the day, with X-Wing/ Tie Fighter/ Mechwarrior, I could play for weeks and not be bored, all mech/ fighter pilot games being released today are all like arcade style, sometimes forgetting that space is 3 dimensional. And despite the technology getting better, the games have gotten worse, they removed what was fun about it, to make it more sleek and simple to use or be just more pretty to look at. I still have the 5 1/2's for Xwing around some where.
It to me feels like a betrayal of sorts to the gamer, when i see these trends in games, the technology might be getting better, but the fun was removed to make way for it. That said there are still some fun very great looking games being released.
But lets look at pokemon, it hasn't changed its style at all, except for a few console arena games or other non standard games no one really cared about. Its remained true to its format going into black and white, and still had that same fun factor (you know getting past how stupid some/most of these new pokemon were, looking at you trubbish, and vommiting anteater psychic type). Yet the graphics were greatly improved, and still capable of providing hundreds of hours of fun.
