I -love- the game Master of Orion II. Every few months I dust it off and spend an entire weekend on it. Because I control the software, I can continue to enjoy it 13 years after the developer folded.
I built a Facebook game a few years back. The company that owns it decided to shut it down. I get messages -every day- from people who are dying to play again. But there's nothing they can do, they don't control the software.
Did you retain any rights, such that you could white-label and de-facebook-ize it, and stick it up on a webpage?
"Oh, yeah. Just get used to it. Notepad++ is so much more modern."
Try a modern editor. Like vim, emacs, or textmate/e-texteditor, and look into what people have built for them. Then tell me you think N++ is more capable.
edit: bah! misreading sucks. delete that last line. Now I need a time machine :\
As a Vim user I feel compelled to mix a shameless plug for my editor of choice in a conversation every time the topic shows it's head. Anyway, I think you misread my comment. I love Vim and I don't even run Windows (to run Notepad++).
A vacuum of users who suddenly need a new service to shovel their money at will be quickly filled by the market.
