You're all right about what you're saying - but there's a psychological aspect that often gets overlooked. In a real room, you have actual time pressure: your brain knows that the 60 or 90 minutes are *real* and ticking away. You feel every moment that passes, and that creates unconscious pressure. Online, you're sitting at home, you can pause whenever you want, and even if you don't - your body doesn't register that sense of urgency. The flow state you get into in a real studio comes from everything coming together: movement, actual room atmosphere, social presence (if you're there with others), and that mental clock that's ticking.
Plus, online formats often build *too transparent* solution paths - the designers know you have limited interaction options on a screen, so they make the puzzles more linear and predictable. In a real room, you can try wild combinations that don't work, and that creates frustration and later genuine moments of success. Try an online studio with a live game master if you get the chance - at least it breaks the passivity and gives you someone to ask questions to again, which makes the whole thing way more engaging.
