Info
PC SHMUP game series made by one drunk Taito game programmer (Touhou fans call him God or ZUN)
Common elements involve a light hearted story, cute girls with silly hats, amazing music and challenging gameplay.
There's been various doujins, fan games, and a few animated producion made off of this series.
Note: The McRoll stole the theme from Touhou!
Note: Always play as Sakuya, she's the perfect-est
See Touhou Wiki for more info.

How To Get Started
Every Touhou noob asks how to get started into the great world of Touhou. Well let me tell you how.
Step 1: Download Embodiment of Scarlet Devil or Perfect Cherry Blossom and play it. There are sites that have links to it and other doujin-style (hint hint) games.
Step 2: After playing it, you may go on to the rest of the Windows games or fan made games.
Step 3: Read, on the wikia, the personalities of the characters.
Step 4: Download images, doujins, h-doujins, hentai, music, fan made music. Whatever. StoneCold2010 can help you on the doujins and images
Step 5: ???
Step 6: Profit!
