I read the old ones first btw lol. Bcs I'm wierd about chronology. And also bcs I have a tab open with all Sniper tf2 fics on AO3 ever, organized by date (bcs otherwise I would never catch up, probably never will anyway) because I'm you know, very normal.
Find all the fics that I'm interested in (by ship or character or whatever) then read them Oldest to newest. In your case - ALL of your sniper or spy tf2 stuff. I think you have like one engiemedic fic maybe (I'm not sure) and that's the only fic of yours I haven't read
I mean, I've noticed some words that you really like using, but overall it's never hindered my "eXpEriEnCe" or whatever. I also noticed that I unconsciously stole some of your vocabulary for my own writing I think and that made ME feel self conscious like daaaamn "uue I'm so unoriginal" or whatever
