I had an idea for a game a few years back, and I drew a few cute little concept sketches for it over a few days. The general idea was that the player character was a young girl whose parents move her out to an island (with like 2-300 residents) and she is a city kid that takes this move pretty hard. She goes out exploring in the forest and finds magical narnia-like gateways to other worlds. I didnt bother to plan any genre or combat or story since im not a developer, but I just did a few environment warmups I thought would be neat. I like the thought of a character with narrow horizons finding themselves through a wide adventure that tests them. The character's working name was Rosa, and the game's working title was Project Dreamer. I havent watched the full meeting yet, just the first 20 minutes, but based on Chris' breakdown, this is what I thought would be a cool development of that idea. So dont read this until you read Chris' idea.

Light ball companion wakes you up. You are a human-shaped embodiment of a program designed to restore code to this world should it become corrupted. In fact, you were designed to be in a statis-like sleep until the world's code became so unstable that your haven would no longer keep you asleep. Once you wake up, companion teaches you the fundamentals of moving, shooting, pointing and clicking, or whatever it is you do to interact with this world. You find out that X number of encrypted files were hidden in inaccessible areas in the far corners of this world (represented by fun-to-model things like ancient pyramids, deep jungles, dungeons, gothic towers, you name it!) but since the world is deteriorating, those rooms/areas are now accessible so you can run around and get them, so that would be the overall goal of the game. As you journey you collect broken pieces of this world, important objects that give the player tiny glimpses of insight into this world's history and significance. Once you restore all X number of encrypted backup files for the wolrds, you use everything you learned to fight/overcome the undecided source of the corruption and restore peace, finally going back to sleep. Full circle hero story. Who knows, maybe youll wake up again someday, more experienced and stronger, ready to face a new threat.
