OpenDUNE VS SRB2

While this is down, check out https://github.com/OpenDUNE/OpenDUNE which is (I think) and early example of a complete decompilation / recreation.

Try OpenDune first: https://github.com/OpenDUNE/OpenDUNE it is free but needs Dune 2 data files.

if you're a Sonic fan, you could play free games like Sonic Robo Blast 2 or Sonic and the Fallen Star which are great imo.

Godot does offer Constructive Solid Geometries that can be used for basic prototyping, and can be exported to Blender for additional work. https://docs.godotengine.org/en/stable/tutorials/3d/csg\_tools.html As an alternate engine, you could also consider Sonic Robo Blast 2 https://www.srb2.org/ as a possible engine to work in. Which has been stretched all the way into making a Kart Racer.

Here are a few free games I've played on my tv: C-Dogs SDL, Sonic Robo Blast 2

I would recommend Delta Touch (Doom engine ports), knights of the old republic 1 and 2 (both support mods on android), Sonic Robo Blast 2 (not on play store but at www.srb2.org ), Source Engine android port (portal, half-life 2, also not on play store but can easily be found by googling it)
