Are Warcraft 1 and 2 worth playing?

‌
I saw that Warcraft 3 is on sale on Battle.net,
and it looks like there isn't much of a price difference for the Warcraft 1-3 bundle..
I've never played Warcraft 1 or 2... I feel like I might not play them even if I buy them, but since it's less than 10,000 won, I'm thinking about getting them..
