I can see your point Tim.
With all the newer games already out, and the eventual games that you have mentioned, RCT3 is really showing it's age these days. It's a shame, but even CS creators are losing interest, as most things that can be made have been already, and with the limitations and the fact that there are graphically superior titles out/coming soon, I can't help but think that RCT3 has gone way past it's prime days.
