Not much of "finding" going on when you are following markers that light up from a good distance when you enter rooms for over 200 collectibles. Quantum Break also had way too many of these. Control probably has more collectibles than RE2 and Gears 5 combined. But collectibles are usually for the more dedicated fans. People who enjoy Assassin's Creed lore probably wouldn't mind finding all its collectibles.
Agree with the first bolded sentence.
Disagree with the second.
Most of AC's collection things are so devoid of lore it's really pointless. I still remember the whole thing with collecting the feathers in AC2 so Ezio's mom can make a toy or something for his younger brother, it was a ridiculous amount of collection for what amounted to be a 30 second cut-scene which had 0% impact on anything in the game's narrative.
Control, on the other hand, has collectible items which flesh out the lore, world and characters. Often you will find notes with information about key characters before you meet them, so when you *do* meet them in the story, you already have a built in idea of what their plot motives are etc (for example, the head of security lady). Yes, control has a lot of collectible items, but my earlier point was that unlike some games, it really doesn't feel like a chore or a hassle to try and find them as they do a wonderful job fleshing out the weird, fantastical world the game has.
RE2 and Gears 5 also have collectible items (diaries, notes etc) which *actually* flesh out the game world. Sure AC has *some* of those too, but most of AC's collectible items can be very easily ignored.
