brent Rollercoaster Tycoon 2 looked fun and weird so I downloaded it, launched in from menu, and got that dialogue box. Ran openrct2 in terminal, and identical box popped up again. There was no message in terminal. Installed from repo; whole system up to date. Advise at your convenience it's far from important. Or if you advise dev tracker, I will take it there. Thanks.
brent update. when I shut the dialogue box, the program (openrct2?) prompted me to install it again, if that's what it's doing. Didn't know what to do, so I hit cancel. Edit: OK, as you see, was greyed out anyways.
davidjharder @brent the problem is exactly what the dialog box is telling you. You need files from the original game. See here: https://openrct2.org/quickstart/extract-rct2-files/linux
brent davidjharder I spent some time there. Saw install directions for about 6-7 distros, not this one. Terminal command for each distro were syntax used for that distro. I gotta go to github I think and get the source files that it's looking for. Once I have that I have to experiment where openrtc2 wants to see them: /var or /opt or /share etc. If I find the whole github source I may as well uninstall solus package and cmake a new one? I didn't see any easy way at that link, but I don't often compile.
aleksvor @brent OpenRCT2 itself is not a full standalone game. It's a reimplementation of old proprietary game RollerCoaster Tycoon 2. The openrct2 package provides only the "game engine" part, and to get a fully working game you need to install original RCT2 first, and then point OpenRCT2 to the installation directory. You can legally buy RCT2 on GOG. Then: Download Windows offline installer. Extract the files from the installer to any directory you want (you can do it easily with innoextract - innoextract -d rct2-installdir <path to RCT2 installer>). Launch OpenRCT2, and choose rct2-installdir in the dialogue. After that it should be up and running.
brent aleksvor thank you. that was thorough. I knew this was a gae you had to purchase. Other than that I knew nothing. MODS: kindly mark SOLVED, thank you.
aleksvor A small follow-up on my instructions: starting with OpenRCT2 0.3.3 (which is already available in stable Solus repo) you don't have to extract the files manually - now you can just point the game to the downloaded GOG installer, and then it will handle the extraction and installation of files automatically. Internally it uses innoextract for this, so now it's automatically installed with openrct2 package.
