Well, I'm sorry to hear about the status of PocketFrog (I guess saying it's dead isn't accurate, but it sounds like it's kind of close). Anyway, on the issue of licenses, I'm not particularly familiar with either, but I can say I like the way you currently license it, for whatever that's worth. As long as I'm not
obligated to give out my source I don't have a preference(and I WOULD give out my source after what I'm selling isn't especially profitable any more, as a matter of fact I'm preparing to release source for Electro and Eliminator shortly... that seems relatively fair to me).
Did you get the RAW extensions I sent you some months ago? I admit they weren't especially good, maybe not even worthy of being included, I only ask because maybe it will change your mind about PF to remember that I at least tried to contribute!
I've looked at all the major libraries that I am aware of and I like PF the best by far, for no other reason than it strikes me as being simpler to use than the rest. I don't want to fight a library when writing a game (I fought with my own before deciding using someone else' is the better approach), and PF just feels comfortable to use, for the most part. I would be quite disappointed to see you drop development on it.
...and so I said to Mr. Gates: "$640 billion should be enough for anyone!"
