100% worth giving the games a shot too! Bullethell games are seriously super fun, if not punishing as all hell.
Ah- I wanted to give my opinion on my favorite Touhou games in response to the posts earlier on this page. I love every game in the series but I think my personal favorites at this point would have to be LoLK and WBaWC. LoLK is so ball-bustingly difficult but insanely fun to play all the while, I will never not feel proud of beating Clownpiece after it took me like 40 minutes of continuous trial and error. It also has one of the best OSTs in the series hands down, Pure Furies is such a fantastic stage 6 boss theme and the fight itself is really good too. I also just love how ZUN threw such a big curveball with the plot when we were mostly expecting it to be the main girls going up against the Lunarians, only for the real antagonists to be invaders from Hell including a fairy dressed in the American flag and a Goddess that looked like she'd came right out of Hot Topic.
WBaWC has such an incredibly fun tone on top of it having a pretty unique OST as far as the mainline games go, playing through the game going with expectations of a more serious story only to find out it could basically be summarized as the gang interfering with yakuza-style gangster disputes and toppling a human uprising all on the same day reminded me of why I'm so in love with the series and it's unique yet extremely memorable sense of world-building and creating fun characters. Also the stage 6 boss fight and her theme are just ridiculously good, ZUN really pulled out all stops with it.
