In my games I usually don't make storyline first. First are scripts, then music and graphics, then maps and at the end scripts. AM I CRAZY??? Once I made a map of a very large forest, which purpose was to connect two towns. Then I made up storyline that happens on that map... Other time I found a very scary spritesheet of stabbed characters. And then made up a part of storyline where some character gets killed, just so I can use that spritesheet...
