I love touhou! I've played every game, except the first 5. I tried one but got bored. I love Imperishable Night, EOSD, Hisoutensoku and Scarlet Weather Rhapsody the most. It's hard to pick a favorite out of those. Probably EOSD. I'm an okay touhou player, I'm good enough to make it all the way to Flandre in extra in EOSD before I die. I love the fan games Meddlesome Magician, PatchCon, Touhou Pocket Wars EVO, and all the flash games on 3-me.net too.
Fav characters... Well.. Flan for sure (Just look at my profile background, lol), but then there's also Cirno, Remilia, Medicine (FTW), Kaguya, Reisen, Tewi, Iku Nagae, Rin, Utsuho/Okuu, Sanae, Suwako, Nitori (I love her), Hina (SPIN SPIN SPIN), Youmu and Yuyuko!
But Flan is the best, with Suwako and Sanae and Nitori at a close second.
I love the music too. Adventure of the Lovestruck Tomboy from PoFV is awesome, as well as Candid Friends, and of course, U.N. Owen Was Her. Don't forget Lunatic Princess, Faith is for the Transient People and Native Faith as well. And Shangai Teahouse, that song that plays during Hong's stage.
God I sound like a crazy fangirl.
