It took you a long time to realise that, but I'm glad you did after all. And now you probably understand where my username comes from.
And actually, I saw The Good, The Bad and The Ugly first and only then For a Few Dollars More and A Fistful of Dollars. I was so sad when TGTBATU ended and was like "Holy shit! There is more of this gold?!" when I found out that this is the 3rd part of the trilogy. All of them are exceptional, but TGTBATU is just simply too good. Dat soundtrack, dat screen play, dat Eastwood.
