I KNOW THIS IS EXTRA INFORMATION NOT EXACTLY ABOUT MAP CREATION BUT I JUST DISCOVERED THAT THERE IS AMAZON LUMBERYARD GAME ENGINE https://aws.amazon.com/lumberyard/ . IT IS OPEN SOURCE OR THEY PLAN TO MAKE IT OPEN SOURCE. THIS MEANS IT WILL BE LIKE BLENDER PROGRAM. OPEN SOURCE AND TOTALLY FREE MEANS THAT IT WILL GROW EXPONENCIALLY. I THINK THE ADDONS TO IT MAY COST A LITTLE OR MORE. HERE IS A BASIC TUTORIAL https://www.youtube.com/watch?v=EVEkqO-ju9Q AND I FIND THAT THIS ENGINE IS VERY CRISP AND CLEAN WITH NICELY LAYED OUT FEATURES. AND ASSETS AND ADDONS WILL GROW NON STOP AND SOON MORE TUTORIALS WILL BE AVAILABLE. BLENDER BECAME SO SO POPULAR AND I AM ALREADY USING IT FOR A YEAR WITH DECENT RESULTS. I HOPE TO FIND NECESSARY TUTORIALS AND FEATURES FOR LUMBERYARD TO MAKE MY OWN GAME. I WOULD LOVE A BLANK RIG TO ADD IT TO MY OWN CHARACTER, AND BASIC MENU I MAY REDESIGN AT LEAST A LITTLE BIT, FREE MULTIPLAYER ADDON WITH NO CODING, AND PREMADE ANIMATIONS AND ADDITIONAL SETTINGS/MENUS FOR INSIDE THE GAME. I NOTICED THAT LUMBERYARD TEAM/MEMBERS/EMPLOYEES ARE VERY PROFESSIONAL AND SERIOUS AND AMAZON IS A BIG BIG GIGANTIC BUSINESS AND THIS MEANS THIS GAME ENGINE WILL GROW AND GROW AND GROW AND MAYBE IT ALREADY HAS EASY OUTPUT FOR THE GAME TO BE INSTANTLY UPLOADED TO MAJOR GAMING SITES. AMAZON HAS MANY THINGS BESIDES JUST SELLING STUFF ONLINE, LIKE AMAZON POLLY THE NATURAL TEXT TO SPEECH THAT IS REALLY GOOD AND FREE UNLESS YOU NEED A TON OF TEXT TO SPEECH FILES TO GENERATE. LOOKS LIKE THEY PLAN TO ADD MORE AND MORE FREE ASSETS LIKE TEXTURES AND MODELS. I PLAN TO INSTALL IT TO SEE HOW IT RUNS ON MY Z440 WITH 6CORE 3.5GHZ PROCESSOR 32RAM AND 2GB GPU. I PLAN TO EXPAND MEMORY AND MAYBE BETTER REFIRBISHED GPU BUT 8GB GPU STILL NOT CHEAP EVEN REFIRBISHED. I THINK AMAZON LUMBERYARD GAME ENGINE WILL JUST OVERPOWER ANY OTHER ENGINE IN 10 YEARS SIMPLY BECAUSE AMAZON IS A SUPERMONSTER COMPANY.
