i'm a huge fan of RCT2 and played it for hundreds of hours. But i think this is needless to point out b/c i suppose everyone in this forum might feel the same way.
The reason why i've registrated here is to emphasize the importance of getting rid of the limitations.
The only reason I'm not playing RCT2 anymore is because every park of mine gets limitated by the fact that you can only build/hire/whatever 255 Units of everything AND that the guests leave the park automatically when it's growing too big. Those two things are VERY annoying.
The things you've done to RCT2 with this mod are without a doubt beautiful...the multiplayer is supersweet. But if you create a park with others, the limitations will be a problem even faster.
In conclusion, what I want to say is that your mod is a real gem i found, but IMO you should prioritize getting rid of the limitations, because that's the main fault of the vanilla game.
