Previous thread: >So what is this game?
Touhou is a bullet hell game made by ZUN. Instead of ship or robots it features anime girls fighting youkai and such.
>Where should I start?
The games until 5 were designed for the PC-98 platform, which would require an emulator. It's recommended you start either with the sixth (first Windows game) or the second game (as the first one isn't a bullet hell) and work your way up from there. Some games aren't your usual bullet hells but should be played anyway.
1: Arkanoid's drunk abusive cousin.
7.5, 10.5, 12.3, 13.5, 14.5, 15.5: Fighting games.
The others follow the basics of the bullet hell genre but usually add a game play twist. Once you're done with the main series you can move on to the fangames, of which some are of excellent quality.
