Here are two resources I found quite helpful...
Start here: https://docs.godotengine.org/en/stable/getting_started/intro...
Or if you're impatient like me you click "Your first 2D game" or "Your first 3D game" in the left bar (whichever you prefer) and go through that -- and skipping back to the intro/step by step when you don't understand something.
By the end of that you'll have made your first game.
From there you just do something extra to it. Mix it up. Start a new project with a different (small) idea. Build small projects until small becomes medium becomes large.
Just like learning anything else, really.
I find this kind of behaviour disgusting. Why don't you do a Show HN on your own?
So far I've played Shotgun Queen and Pawnbarian. There's also Ouroboros King, Demoncrawl, The Rookery, Passant, Chess Survivors, Gambonanza, Mind over Monarchy, and many more.
The mechanic is fairly simple for this board game (not computer/video): A standard chessboard and chess pieces are used, with a custom deck of cards for each player. Before moving any pieces, a card is revealed that effects enhancements/restrictions/story/etc. The selling point would be banking on the creativity of the deck, of course. If there is anybody that could run with this idea (if in fact original, which I doubt) before I do, I'd love to hear about it! ♟
They are both chess-inspired and roguelike.
IMHO this is a completely normal "hey I've been doing something similar" response. Why are you so aggressive about it?
