There's a limit of 10000 entities in total (including guests, staff, and coaster cars). There is also a limit of 256 rides on the map. These limits can only be removed with the new save format (which is still in an experimental stage), as SV6 files don't have any room for more data - although the new format isn't truly unlimited either, it just greatly increases the limits.
I have been a fan of the original game since I was a kid.i came across open rct2 on YouTube.sorry im so late to the game..any way to max the advertisting,unlimited workers and guests in the park.and remove the limit of number of rides aloud thanks.i like to use the advertising to get as much people in my park as possible
If anybody is interested in improving the park, e-mail me your user name and hash and I will add you as an admin to my server. To find your hash, go to your OpenRCT2 directory and look inside the keys folder. The hash number will be next to your user name in the .pubkey file. I originally left the server completely open for anybody to mess with and I already had too many trolls mess around with the park (go figure) lol.
