>>717308283>Gacha and Auto Battlers basically replaced TCGs and MMORPGs.Hard to replace things that are still actively made. Hell, Square Enix still maintains three MMORPGs in addition to gacha ventures.
The rest is a lot of the same- these things aren't really being replaced. Not as prevalent, sure, but a lot of these things are still built on what was there 20 years ago, and gaming has no evolved that significantly.
Compare the drastic changes of before
In the days before and during the Atari, most games were still built in the style of arcade titles, being endless in some capacity. During the NES, that shifted to games with designated endpoints- they could have a second quest, but they still had endings.
By the time of the PCE/Gen/SNES, this saw a full tilt towards games with narratives and far more experimental titles, but I would still consider that in line with the later NES works.
The arrival of 3D completely changed things though, which is why the fifth gen is very distinct from the sixth gen, it's probably the most experimental video games have ever been.
The sixth gen is when trends solidified, online started to become commonplace, and then in the seventh gen, online solidified, DLC arrived, microtransactions began in their infancy, and there's less evolution and more standard growth to today. That's why I don't view the trends of today as distinct enough to really warrant labeling gaming from the mid 00s on as retro.
The first thing to likely become retro in this era will become the concept of distinct consoles as a whole, what with steam coming to Xbox (and likely PlayStation as well if Sony is smart), leaving just Nintendo and "Game Machines".
After that, who knows. We could very well be waiting for SAO style fulldive VR before gaming notably changes again.
