I'm trying to muster up the courage to pursue the realization of this multiplayer turn-based RPG that my friend and I dreamt up years ago. I lack experience with net-code and also large-scale architecture and also RPGs just have quite a large amount of game logic and it feels very daunting. I know how to divide the problem into smaller problems and I've made other games with non-trivial amounts of game logic but I still am struggling and I'm not really sure why. I feel a lot of anxiety when I look over my code for what to do next and then come back a week later (rinse and repeat). I feel internally that getting over this hurdle will be a large stepping stone for me.
