I'd do it for free and give it to Fdev to incorporate (and I'm betting thousands of other potential modders would too), but Fdev won't let us.The thing is not walking around it's doing stuff, otherwise it's 15 minutes of "OHHHhhhh...that's luuuvvly" then you never go back inside he domed forest-world interior that took 1000+ man-hours to put together and integrate.
Also, that's maybe true of you and many others (not going back), doesn't mean other players wouldn't. I was always getting out of my chair and walking around stations, eva-ing around ship hulks in X4 - not much to do there, it was just enjoyable.
