Feels weird to answer "No" to that despite Remilia Scarlet (and the whole Enbodiment of Scarlet Devil setting really) being one of my earliest and biggest inspirations. I used to be in the series' orbit, enjoying the soundtrack and the various character designs and lore bits and viewing tremendous amounts of fan art and music but I never really played any of the mainline games (not counting the fighting games).
Some of the character designs were more of a miss than a hit for me before, sure (e.g. Reisen, Nue) but Ten Desires was the first where nearly all the new characters felt a little… mediocre, except for Mamizou, she is perfect. Legacy of Lunatic Kingdom's roster was the first time that a Touhou character made me go 'bleeh' and afterwards I mostly dropped off. I've seen some nice designs in the newer games since (e.g. Narumi, Keiki), but to me the name 'Touhou' will mostly invoke that era between 6-14.5 or so.
