Why are you selecting SDL_NET here, and then provide an option for the
network support below? This looks odd.

What is under GPLv2+ and what is under a Freeware license?

Even if it was working, it is not a good solution, because it does not
integrate properly with the download and licensing infrastructure.

We have the <pkg>_EXTRA_DOWNLOADS, but it works only if the file has to
be downloaded from the same site.

So my recommendation would be to create a separate package called
opentyrian-data, that installs this. And unless the data is needed at
build time, this package can be a runtime dependency, i.e selected from
Config.in, but not mentioned in OPENTYRIAN_DEPENDENCIES.

Other than that, it looks good.

 Why not simply http://www.camanis.net/opentyrian/tyrian21.zip ?

 DOWNLOAD expects the full URL as the first argument. The optional second
argument exists for cases where the local file should be different than
the base of the URL (e.g. if it contains question marks or other madness).

 Everything in target is already stripped automatically at the end, so
it's usually not needed to pass this.

 We prefer to install everything in /usr/bin.

As I've replied separately, packages should not directly use the
DOWNLOAD macro, I believe.

Except if the package does its own stripping, and defaults to the host
strip to do this. In this case, we can either pass STRIP=/bin/true, or
pass the real STRIP value.

I think I will create an opentyrian-data package to solve my problem, as
Thomas advised.
(sources and data aren't in the same server directories)

yes but OpenTyrian Makefile otherwise uses host strip and fails to build.
So I will use Thomas method (STRIP=/bin/true).

prboom & rubix packages already explicitly install everything in
/usr/games/... What should I do ?

Send a patch so they install in /usr instead? ;-)

Those are packages that went in a loooong time ago, even before Peter
took over maintainership, so they might not follow the current
conventions.
