Is it worth collecting sticker album cards these days?

What do you mean by worth it - collecting them for fun or as an investment? If it's for kids, yeah, it still works great - they trade them, hunt for them, it's a simple way to play together without screens. If you're thinking you'll make money off it, forget about it: the market's oversaturated, rare ones are worth something but you'd need crazy luck and patience to resell them. Collect them only if you actually like the idea, not for anything else.
