Well, it was mentioned in the Spring Thing, and I think it'd be a great feature to have, so...
Yeah, I'm not sure how hard this would be to implement (probably hard, so by thus less likely to be implemented) but I think being able to, with Author's permission in time of publishing, download a story game in a file of some sort on a computer would be a great feature for the site to have.
Reasons for having a feature like this would be as follows: A) Firstly and most importantly, being able to read stories on here 'on the go' (without Internet access) would definitely be fun, especially the longer stories. B) It would allow some stories to 'survive time'/the server. And C) It might help improve the reading fan-base of the site/make the site more popular.
So, thoughts?
