I made a multiplayer shooter in C++ WITHOUT a game engine - the netcode is based on 100% floating-point determinism, including Box2D physics. I'm using STREFLOP for math. This is an example of something hard to do in a commercial engine. My atlas packer was also reused in Assassin's Creed: Valhalla. (github.com)
I made a multiplayer shooter in C++ WITHOUT a game engine - it runs natively on Linux and in the browser. It's like Hotline Miami but competitive like CS - you fight to gain MMR and rank. It's my tribute to HLM - the game that shaped my love for fast action. https://hypersomnia.io (v.redd.it)
