Please note that the C201 ARM laptop Minifree sells is not certified by FSF
and as far as I can tell it's not certifiable, because it ships with Debian.
Debian is known to facilitate nonfree software through official repos and
docs. There might be other software freedom problems with Minifree's C201,
problems that we can only find with the help of an owner of that laptop.

Minifree missuses the term "Respects Your Freedom" to mislead users to think
their C201 has the FSF's Respects Your Freedom certification, like their X200
and T400 have.

Minifree also tries to mislead people into thinking that the C201 they sell
is okay in terms of software freedom by saying: "Your Libreboot C201 obeys
you and nobody else. Even Richard Stallman uses libreboot!" At the same time,
on the libreboot website Leah Rowe, the person controlling both minifree.org
and libreboot.org says: "There is a huge cult of personality around Richard
Stallman" and "Many - a lot of - FSF followers are fanatical, to the point of
extremism".

Previously their X200 and T400 have been certified by FSF while those were
shipped with the fully free distro Trisquel. But now they ship with Debian
and BSD: "Our laptops come with Debian GNU+Linux (or BSD)". Debian is not
fully free and so far we know of no fully free BSD distro.
I'm afraid Minifree is not ethical as it used to be. They install systems
that don't follow the Free System Distribution Guidelines of the GNU Project,
but use the names of FSF projects (GNU), campaigns (Respects Your Freedom)
and president (Richard Stallman) at minifree.org to convince people to buy,
while at the same time attacking FSF, GNU and RMS at libreboot.org.
Back to the main question in this topic, if you are looking for hardware that
can help you test games, a laptop that can only do software video rendering
is not the best choice. Instead of the Asus C201 laptop I recommend you
choose a ThinkPad laptop preinstalled with libreboot and a fully free distro
at your choice (if Trisquel is too old, you can try Parabola which is
bleeding edge): https://tehnoetic.com/laptops - these laptops are all FSF
certifiable and are or are about to be recommended by FSF as part of their
Ethical Tech giving guide: https://www.fsf.org/givingguide/v7/ I believe that
the Tehnoetic X200 Tablet would be a good fit for a game developer:
