Manic Mansion, MM2, The Cave, Thimbleweed Park, and now TWP2: Gilbert's. Possibly also some of the many kid's games he did https://en.wikipedia.org/wiki/Ron_Gilbert#Games
Broken Age is the only one of the many, many games Tim Schaefer lead that does it. https://en.wikipedia.org/wiki/Tim_Schafer#Ludography
I have generally found it to be some tedious bullshit that stretches out the length of the game far, far too much, and I grew up playing a lot of these point and click adventures.
Day of the Tentacle (which coincidentally I've replayed in the past week) executed the multiple characters mechanic the best I've seen, since each character was confined to their own area (past/present/future) and you could instantly pass items between them.
I've not played that in decades, but I remember liking the mechanic. For the most part it wasn't much different from one character with more freedom to move between areas (timezones in that case), but the need to pass objects through time added some variety and humour (send hamster via freezer, but then how do you warm it up again?).
Thimbleweed park is, if anything, on the easy side of the genre. Not quite as easy as Loom, but it's still on the easy side, and with a built in hint system. Day of the Tentacle's main problem is dependence of US culture. Just like the old "monkey wrench" thing in Monkey Island 2, using an actual monkey as a wrench. Still, in DoTT, you get in-game dialogue that will basically teach you some of it, although it doesn't work quite as well.
The complaint would make more sense if it was limited to Zak McCraken, as that one really s quite tough and random.
