Creatures Internet Edition
Nothing exciting to say about installing the game & running it with the bundled SDL-1.2.
But things get really nasty if you want to use you system libraries & sdl12-compat in particular…

$ creatures3 Welcome to Creatures 3! Inconsistency detected by ld.so: dl-version.c: 204: _dl_check_map_versions: Assertion `needed != NULL' failed!
lc2e is a very old ELF binary, and unfortunately it is very broken by modern standards:
- it contains explicit symbol-version requirements against
libdl.so.2(readelf -V lc2e) - but it doesn't declare a dependency on
libdl.so.2(readelf -d lc2e)
You can use patchelf to fix this:
patchelf --add-needed libdl.so.2 lc2e
But why does it work with the bundled libSDL-1.2.so.0 ?
Because that library has a dependency on libdl (and that make the loader happy), while any modern versions (be it a real SDL-1.2 or sdl12-compat) won't. Again: why ?
Because with the release of GLIBC 2.34 in 2021, libpthread, libdl, libutil, libanl have all been integrated into libc; new build does not link with them anymore.

This is a fun one. lc2elib.so use some private symbols that are not part of SDL-1.2’s public ABI, that are exported by the bundled libSDL-1.2.so.0, but that aren't exposed in any build of SDL-1.2 made in the last 2 decades.
