For some, that's an easy thing to do. You write a load of stuff and when you get to the end, you're done or perhaps you're doing it as some sort of competition and have a time limit. For philanthropists like us, we have even more freedom. People aren't paying for it, so we can upload often and do not need to do quality checks quite as stringently. You also don't need to keep a product line alive with regular updates and new products.
There are lots of us here that just doing because it's good fun to make stuff to play. I'm getting through the next version of at the moment, redoing all the graphics (so it looks better printed) and improving some of the more dodgy rulings. But where do I stop? When do I say "That's enough, time to upload it."
When do you know it's enough? when you're sick of it?
