openrct2 & game-data-packager

Hi Mathias,

I missed the closure of your ITP bug #808945 -
"openrct2 -- An open source re-implementation of RollerCoaster Tycoon 2".

There's some GOG.com automation in the OpenRCT2 engine itself
but for other scenarios the users are left to play with
lgogdownloader / innoextract / unshield / steamcmd [*]
on the command line instead of playing their game:

https://openrct2.io/getting-started/index.html
https://github.com/OpenRCT2/OpenRCT2/wiki/Required-RCT2-files

I've added today this game to game-data-packager... as discussed back in 2015.

https://salsa.debian.org/games-team/game-data-packager/-/commit/26405eee863eeb407998a79f67577659f5f1e328
[*] game-data-packager will call these same tools itself


A tiny Debian-specific patch to openrct2 to make it first
checking for files into /usr/share/games/roller-coaster-tycoon2
before asking the user where they are would be extra nice.


Testing of GDP against both GOG.com & Steam would be a plus too.
I need the details of the setup.....exe archive, it just can't work now.

Greetings,

Alexandre
