SRB2 VS jak-project

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.

Sonic Robo Blast 2: https://www.srb2.org/

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)

Jak and Daxter

But now there's NSA's Ghidra which has accelerated decompilations/reverse engineering a ton, it means that within a few years any active community can fully reverse engineer into human readable code and make major changes, it's why now there's a Driver 2 PC port and a Jak & Daxter PC port with 2 and 3 being in the works despite these games having basically no community before it, Nintendo games have a bigger modding community and a lot of games are on the way to being fully decompiled (bonus in that some games share a lot of stuff, so as one project completes it also makes it so that multiple games also advance faster
