I would say not really. For one thing, the early days of gaming held onto many elements from arcades where games were meant to be consumed in somewhat bite-sized chunks (Atari, NES, etc).
A big factor for multiplayer games is the somewhat modern obsession with matchmaking and character intro/pick screens. When I was a kid, I could hop into a game immediately for a 15-20 minute deathmatch session of Quake 1/2/3 in any semi-populated server then leave whenever it was time to do homework, etc.
Last I tried Quake Champions, the newest installment in the series, you spend roughly 1-5 minutes in a matchmaking queue then another 2-3 minutes (or more, it was pretty bad sometimes) in some intro/loading screens, then another minute or two in a pre-match warm-up. So even in the same genre's case you're already potentially 8+ minutes sunk into your 15-20 minute 'quick game' period.
To make matters worse (again because of matchmaking) you are penalized if you have to leave before the completion of a match or if you go idle. Usually this penalty is applied as a low-priority queue the next time you try to matchmake which just compounds the problem from above.
Don’t forget the 2-3 minutes it seems to take to even load the game. QC would be so much better if you could just load it (quickly) hop onto an already-playing game, and skip all the intros and statistics. How did a franchise like Quake backslide so badly?
I think the developer/publisher are just responding to market pressures.
Quake Live (at least for its first few years) was relatively pure and old-school, including in the ways mentioned in this thread, but it was only moderately popular and didn't seem to do well financially. The most (financially) successful modern games tend to focus a lot on extrinsic motivations to play -- including character progression, unlockables, gambling crates etc., but also things that give extra context to individual matches, like statistics and ranking points -- rather than just the core gameplay. People also have less tolerance for being the newbie who loses 100-0, and expect to be matched against players around their level.
Not all of these things are relevant to your question, but some of them help to explain the trend toward lobbies, matchmaking queues, and other obstacles to just clicking on a server list and jumping into a game.
The Nintendo Switch has an excellent selection of more 'casual' games. Super Mario Odyssey reminded me a lot of the games I played as a kid.
