The community...
First if not for the older RCT3 community, the product would have disappeared faster than a nat chasing cows hooves on the range. Nat's

don't last long.
The future relies primarily on the newer now 5 open source communities making 3D TPG's "Theme Park Games." That is the future is the open source. TORCG3 aka RCT3 will thrive for a while, but overall without new coding is dying a slow but eventual death. In the coming years it will become forgotten history sadly, but that is reality.
Consider that TORCG3 had about 75 rides. The TPB3D community already is pushing past 150 rides in their repository, more than double the original rides, and the quality and accuracy of the tpb3d rides easily rivals what the TORCG3 community originally offered. List of trees, let's talk about two hundred tree types to get started and about 5,000 plus eventually.
Coding, TORCG3 aka RCT3 was geared to 32mb video cards and slow processors with 750 mhz and 500k ram. That was the year 1994 and coding had started several years before that so think maybe 2001, those machines were even more ancient by today's standards. TPB3D is geared towards 256k cards and up, 2gb ram machines and fast processors to start, a major difference, and so are the other open source projects out there.
Here is the beauty of a community. In TORCG3 we got very well modeled work by the frontier team on themes, but limited themes. In the open source variant we have over 60 themes and more proposed with modelers already making stuff on their own time. The world as a resource can easily be unbeatable especially where imagination is concerned. What has kept TORCG3 alive has been the entire TPG world desperate for a publisher who abandoned them. It isn't Frontier's fault because they got paid as the professional developer they are or as a contractor, fair enough. Instead it falls on Atari for abandoning their many customers, one of whom I am.
And so you will get RCT4, just a few things to note here.
1.) It won't be owned by a corporation, it will be owned by you.
2.) Support will be free for life.
3.) You will get tens of millions of rides.
4.) Endless expansions scenery sets and themes.
5.) Consistent innovation.
6.) It will just keep getting better and you are an owner as is everyone on the globe and space station too
Oh, I forgot 7.) it has a different name now

(sorry Atari Corporation) five of them and a main one too
Welcome world, here we come.....2010!
