is quake good for anything other than fps games doe?
at that point just make shit using the source engine.
needless to say but the quake engine doesn't support modern technology we could benefit from today however, and can easily have bad performance on modern and low end pcs if you're bad at optimization. as for the 2016 computer argument, im not sure if i agree. i find the suggestion to use quake funny but ultimately impractical, as self admitted, there are no tutorials and the language is probably very hard, unlike GDScript.
