SRB2 VS BrogueCE

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)

For a long time, most traditional roguelikes were free (although there seem to be more on steam lately). I think Brogue is a good place to start; it isn't too complicated, it has some nice quality of life stuff, cooperates with a mouse, and its pretty for its genre.

I only play community edition, and my ascensions have been lightning, conjuration, teleport and some reaping combinations. My mastery was teleport with invis/reaping support. Multiplicity weapons are good (spear, rapier) but i tend to get ambitious and play hard for a mastery and screw it up.

Your best option is Brogue (community edition), in my opinion.

Brogue

Brogue is another good option if you're down with rogue-likes, can basically run on anything (& has an Android version).

Adding Brogue [1] to the list. Neat and very well balanced.

Broge, Angband, C:DDA, Dungeon Crawl Stone Soup, are some options.
