What is Platform eXtended library?
It is a latest successor of Aspyre Sphinx 3 library. Main purpose of it seems to be a Graphical Library with some additional functionality to help you creating 2D/3D games or scientific applications.
It can be used both with Delphi and FPC. And unlike many other libraries Platform eXtended library can even be used on many SingleBoard computers.

There seems to be more engines and frameworks than actual games.

Yep. And some of them seems unmaintained.

Anyway, you may want to add Allegro.pas, and may be later MinGRo.

SDL | Visual C++

What? SDL is written in C.

I guess you could separate SDL into SDL1 and SDL2. SDL1 support comes out-of-the-box with FPC. For SDL2, ev1313's units (link) can be used.
