Where can I see the souvenirs and what drops they include?
its funny to play pickem but i think dont worth it
objectively worth it? no.
you see this as a pickem with some added small bonuses? worth it.
no, buy urself mcdonalds instead
If you mean money-wise then no, it's not worth it. Since they are guaranteed there will be much bigger supply which will decrease its price, plus no cobble so pretty cheap souvenirs.
ofc worth, it would cost more if u only have to buy the stickers for pickems
