Billion and one~ ;D and then I'm like:
Two. I can't pick between fantasy and horror, so I open them both.
2-3 but usually that's because I remember I have something set the way I want it in another project and it's easier to copy than to redo it all
1, sometimes 2 when I need to find some of my older scripts or learn something from my old projects
I'll be honest... 5 or 6 because I'm always practicing several things in ruby at once. Well, and I'm also really unorganized so I have a little bit of resources here, some there, a bunch of projects I never touch etc. lol
Just one... One is more than enough for me. Anytime I have ideas for other projects, I write them down and keep them in a notebook. I then tell myself "if I finish this project, I'll work on these other ideas".
One, well unless I'm checking something from the other game or copying some scripts.
