    Dungeon Craft

    Updated emulator of Forgotten Realms: Unlimited Adventures

    Up to date code, including latest engine and editor releases: https://github.com/grannypron/uaf Dungeon Craft Community Forums: https://forums.goldbox.games/index.php#c8 Dungeon Craft is an adventure creator that emulates the Advanced Dungeons & Dragons Gold Box RPG's released by SSI. Initially designed to be a "more unlimited" version of the Forgotten Realms: Unlimited Adventures (FRUA) game editor and engine, it has far surpassed the capabilities of the old FRUA system. The editor is used to configure art, items, monsters, spells, special abilities, classes and races.. Each adventure is self-contained and doesn't require the editor to be played. The editor is extremely versatile and the databases are completely designer created allowing easy additions and modifications to spells, monsters, items, classes, races and special abilities, and are exportable to be easily shared with others or used in other designs.

Finally, ZQuake is a derivate of QuakeWorld client made by Id Software. This company has created the Quake game itself and later on released the source codes of game executables under GNU General Public License. Because id Software didn't release the whole game for free to the public you still need some of the original files from Quake to play QuakeWorld using our client.

    DarkForestGo

    DarkForestGo

    DarkForest, the Facebook Go engine

    darkforestGo is an early deep-reinforcement-learning Go engine that combined a convolutional policy/value network with Monte Carlo Tree Search (MCTS) to play the full 19×19 game at a strong amateur level. The system couples fast GPU policy inference with CPU or GPU-assisted tree search so priors from the network guide exploration while search refines local tactics. Training pipelines mix supervised learning from human professional games and self-play fine-tuning, allowing the model to learn opening patterns and endgame tactics beyond simple pattern libraries. The codebase includes tools for parsing classic Go formats, generating training examples, and evaluating models on standard test suites and online servers. A KGS/online client and match runner make it practical to stage controlled tournaments or continuous rating evaluation. Although later projects (like ELF OpenGo) surpassed it in strength, darkforestGo remains a historically important, clean reference for neural-MCTS Go systems.
