So, one of the things I have on my bucket list is to create a proper megadungeon for OSR tabletop roleplaying stuff. And I have tried doing so already, but each time I got stuck near the beginning, since I had no clue how to stock the dungeon rooms in a sensible and coherent manner.
Heroes of Might and Magic 3 is a game that is close to hearts of mine and many other people. The community of this game, while relatively small and niche, is still going strong, even having cash prize pvp tournaments! There are also many in-game improvements thanks to various mods.
That being said, there is one thing that has little support in HoMM3, and is a thing that is sometimes being asked about – that being free for all player vs player gameplay. There are few maps and random map templates that properly try to support this type of play – and well... the mechanics of HoMM3 work against the FFA format being fun, due to several pretty major problems that show up specifically in this one format of play.
