Even if it's a set I would never have purposesly collected, I love when I go from never having heard of a set, to completing it. Today, we get that with 1988 Dinosaurs Attack from Topps.
Learning! Love when they sneak some good old fashion learning on cards, like how to say the names, size of the dinosaurs, and a decent write ups too.
Would I ever have tried to collect this set...nope...never would have been on my radar, and if I didn't get all of it, I wouldn't have gone to try and finish it. Now, will I keep it? Absolutely!
