I wonder how many threads on the codex can be filed under "things were a lot better when I was 13"
Or just "thing were a lot better the first time I encountered them". A big part of my enjoyment of the original Wizardry, back in the day, came from the sense of open-ended possibility. It seemed like anything was possible. After playing enough video games you inevitably start to see the bones underneath and that erodes the sense of wonder. Maybe just file this under "getting old sucks but it still beats the alternative".
If that's the case why am I able to go back the these old games that I supposedly only like because I am seeing them through rose tinted glasses, or because of the novelty of my first experience with them or what have you, and still enjoy them? Sometimes enjoy them more or in different ways than the first time I played them because I have over the years developed an appreciation for the technical aspects and artistic subtleties I didn't fully appreciate in my youth. And certainly enjoy them more than most of the recently released games I am playing and experiencing for the first time (with all kinds of awful new mechanics I am experiencing for the first time). Important to note that I'm still perfectly able to enjoy new games, regardless of if they offer a completely new experience (say The Talos Principle) or if they are similar to games I experienced before (Prey 2017, the new Hitman games), so long as those games are good.
Conversely, there are plenty of bad games I played for the first time as a kid and really enjoyed, but I don't claim these games are good under the influence of rose-tinted glasses or whatever. I might remember my experience with those games fondly, but the games themselves are not good. There is a thread about Deus Ex IW someone started recently where I mentioned that I loved playing IW as a kid because it was my first experience with that kind of game, but when I go back to it now it is clearly a terrible game, whereas I can still play the original DX and enjoy it despite having played it for the first time years later when I was older. Same goes for Hitman Blood Money, a game I thought was the best thing ever when I first played it, but after playing the earlier games in the series later I find it to be inferior both mechanically and atmospherically, and I also find Blood Money to be inferior to the new games in the series (a combination of opinions and circumstances that should be completely impossible for the drones who try to brush the concept of taste away with claims of nostalgia and rose tinted glasses). RE4 was another game I thought was awesome as a kid, but I can recognize now that it is a shallow game that ruined an entire genre; the QTEs that I experienced for the first time in that game when I was 13, and which gave me an enjoyable thrill the fist time, were shit then and are shit now.
After playing a lot of video games (or reading a lot of books, looking at a lot of paintings, watching a lot of movies, etc etc) and getting older yeah maybe some of that magic that is only possible to experience through naivety and unawareness is lost, but it hopefully gets replaced by a deeper, critical ability to appreciate and analyze the "bones underneath." You may not be taken in by the same childhood wonder that is only possible when you still can't totally separate reality from fiction, but you can experience a new sense of wonder towards all the ingenious techniques and artistic choices that went into the work.
This is not a bad thing, it is how one develops a discriminating taste, which in turn is why a thread like this can exist where people can write in-depth criticism of a game and discuss it on a level that would not be possible when you're a kid (until of course inevitably some bozo comes in and drops the trite "you only liked this because you played it as a kid" line). I resent seeing people rely on the nostalgia and rose tinted glasses argument (which seems to be a very popular thing to do now days), because it tries to handwave away the fact that people can develop a discerning taste about what is really good and what is really bad, which is more important now than ever with how much absolute shit is being produced these days.
Small addendum related to what you said about Wizardry, I actually bounced off Morrowind the first time I played it as a kid because of how open ended and seemingly incomprehensible it was, and it was only relatively recently I was able to get immersed into that game, despite the fact that now days I am fully aware of how limited the game world is I now appreciate all the ways in which they were able to hide that and tried to create the illusion of a large, exotic world.
