I'm not sure what if have now that isn't already available. But I tend to be a hoarder about saving found tracks, data files, and parks. So its likely that I may have more you would want to add. If you want, I could zip up my entire data folder ( I think my main folder has over 16,000 files. But I likely have more on my portable hard drives. Plus I played the original games way back in the day when they first came out and I know I saved data files on DVDs back then. I'd have to hunt those out, they're packed away somewhere in our junk room. They might contain more content that I've even forgotten about.
Now, the issue is in a bit of a wait. I'm currently hospitalized at the moment, hopefully just a few days or so. And I can get that first file to you as soon as I'm out. I can upload it to my Dropbox or elsewhere. I think when I checked the contents, it was a bit less than two GB.
Im not even sure, can we send each other pms on here. I can PM you my email so you'll know who I am when you get the file.
