While I do agree with most of what you say especially the part in which you say that realistic games age badly, I disagree with you in your third point. The problem are not the new games or consoles but you. As one grows older he makes a fine line between past and present. The past seems magical a time when games were amazing. The present is a time riddled with problems were games lack magic. Many go through this phase explains why many gamers collect old consoles to relive that time when games where magical but intact they have grown into adults and changed.
I'm 34 and have been playing games since I was 4 which means I've experienced every generation starting with Atari 2600 AS IT HAPPENED and let me tell you something, that "magic" thing you speak of? I had it all the way up until the this generation when I bought a PS4 at launch. It has nothing to do with youth for me, because I haven't been considered "young" for ten years.
For me, the PS4 and Xbone lost that magic when they released consoles and software that were shiny versions of what we have been seeing for years now. Nothing fresh, nothing new. It took a few months before the joy of the new toy I bought wore off and I was left bored to tears. Not that the games sucked, but because, like I said..been there, done that.
So, I went with Wii-U instead. I got the MK8 bundle, and The Wonderful 101 and...there is was...that magic again. You can't keep playing the same murder sim/FPS/mature/dark hum drum software over and over again without it getting old imo. Back in the day, each generation meant brand new experiences and THAT was what made the magic happen. Without it...meh...
I am sure that gaming to you is not the same as it was when you was 4. Back then gaming meant a big part of your life. Back then every gaming moment such as getting a game, finishing a game, beat a difficult boss etc was precious. This is what the op is talking about and since he is just 16 he is just finding out that gaming seems to have less meaning to him then when he was a child. And by the way this gen is trying to find a new gerne as you can see new games are taking over and Cod and Ac are being left behind. My advice would be to give this gen some time to settle down. And you may also be finding Mk8 and the wonderfull 101 especially Mk8, enjoyable since you may have rarely played any of the previous versions.
I understand what you're saying, but it never really happened to me. When I was 16, I was gaming on PS1 and playing DK64 and it blew me away. I didn't start losing "it" until the middle of last generation when things started to get stale. The Wii bubble had popped and it seemed like innovation, for the first time, left the building.
As for MK, you're right about that. I loved the first one on SNES, bought the Gamecube version when it launched, but that was it. I don't think MK is a franchise that you can buy every time it drops. They play too similar to one another imo. It's better to space them out like I've done.
The Wonderful 101 on the other hand, really IS fresh. Name me something on PS4 or Xbone that plays and feels like that game. There isn't anything like it. The same goes for Pushmo, or Art Academy (I know it's not a game, but I'm using it as an example of software that FEELS different), Pikmin 3, Miiverse, a tablet controller....it's just all so different from the original Wii. That's what I grew up with. Each generation was vastly different than the one that came before it either in software, hardware or both. The PS4 and Xbone are (and this is just my opinion) too much of the same. The consoles feel the same. The controllers feel the same. The software feels the same (and in some cases, ARE the same)...it's just, stale.
I suppose if someone just got into gaming, they wouldn't have the issue but, for a vet like me, I need that freshness to stay invested.
