Nah, that's a huge effort. As long as the codebase is workable without a major refactoring, things are just as fine as they are. And frankly, Mr Fox needs to start making money somehow!
Even if he did, he'd have to limit himself to an ancient version of Adobe's AIR (2.6 and lower) if he wants to maintain Linux compatibility (Adobe no longer releases AIR for Linux).
Any serious rewrite of the game from me would be monetized in some way; I didn't start on this project without having thought about its implications.
As for Linux support, AIR 2.6 isn't so ancient that it's a great inconvenience to support. I think I can switch a single variable in my development environment to build for 2.6. AIR 2.6 was released in early 2011. LCS is built on a library that hasn't been updated since 2008. "Ancient" here doesn't mean old and broken, it just means there's new and better. That's something anyone making or playing ASCII games should be very familiar with.
Even in the worst case, it's easy and common to port games between AIR and Flash. Flash 11.2 is stable and will be getting security updates for years, and Adobe continues to support new versions of Flash for Linux through Chrome.
Anyway, let's get off the topic of LCS re-implementations. No-one wants to do it, and there's no reason to do it.
I want to do it, and re-implementing the game has a huge benefit in that this would allow support for mobile devices. Early this year, I built a framework that simulated the console presentation in AS3, adding mouse support so you can click or tap menu options like links, instead of having to do hotkeys. I am actually quite interested in making LCS playable on all platforms without difficulty, able to be ported to mobile devices, and with a rich and robust foundation for any mouse/audio/graphics support it may want.
That doesn't mean I'll necessarily take the time to finish this sort of rewrite -- I'm not currently doing it, and the amount of work involved makes it less likely that I can just do it as a lark. I don't want to encourage people to
expect this to happen. But I also don't want to discourage discussion of the idea, and I certainly don't want someone else to speak for me and claim nobody is interested in doing it. I would consider it moderately improbable, but a lot of improbable things have happened over the course of this game's development.
