I am currently in High School and thinking of making a game for the Skills USA Game Development competition. I was thinking of making a basic 3D game similar to Minecraft. Obviously it will not get even close to Minecrafts level, but I want it to feel sort of like Infdev or earlier versions of the game. I have around 2-3 months to try to make something. I have experience with other software and have programmed games using Unity for around 2-3 years. Any recommendations on how I could get started? Thanks!
A voxel style game like minecraft does make for a fun capstone project, generally the requirements to run such a game is noise-based terrain generation, chunking, and greedy meshing. Noise-based anything Godot and every other game engine should be good at, chunking similarly should be easy depending on how you want to implement it. The last, greedy meshing is more complicated and may require looking under the hood for most game engines to generate a simplified mesh, you could try to implement this last. Godot does provide a couple of options of dynamic mesh creation.
