    EE Keeper

    EE Keeper

    EE Keeper is a saved game editor for Baldur's Gate Enhanced Edition.

    EE Keeper is saved game editor for Baldur's Gate: Enhanced Edition and Baldur's Gate II: Enhanced Edition. This project is a continuation of Shadow Keeper, originally released by Aaron O'Neil in 2000 for Baldur's Gate II: Shadows of Amn and Throne of Bhaal. This version will still work with the original BG2. Currently, it will only work natively on Windows, although it has been tried through Wineskin on Mac OS X and currently works, though no guarantee is in place that this will continue to be. Maximising that support is a priority, however. Please note: unless otherwise stated, EE Keeper will be archived in Zip format and uploaded. Please note, any support ticket that is created should be watched in case any extra information is needed. If you do not plan to keep and eye on your ticket and you have an account on the official Baldur's Gate forum, please be sure to provide your user name with the ticket in case any further information is required.

    Tiled

    Tiled

    Flexible level editor

    Tiled is a free and open source, easy to use, and flexible level editor. Tiled is highly flexible. It can be used to create maps of any size, with no restrictions on tile size, or the number of layers or tiles that can be used. Maps, layers, tiles, and objects can all be assigned arbitrary properties. Tiled's map format (TMX) is easy to understand and allows multiple tilesets to be used in any map. Tilesets can be modified at any time. Tiled is a general purpose tile map editor for all tile-based games, such as RPGs, platformers or Breakout clones. Tiled was originally written in Java. In 2008, work began to develop a faster, better looking, and easier-to-use version of Tiled based on the Qt framework. This decision was made as the Qt framework has a greater feature set than is offered by the standard Java libraries. Before you can compile Tiled, you must ensure the Qt (>= 5.6) development libraries have been installed as well as the Qbs build tool.

    Dungeon Crawl: Stone Soup

    Dungeon Crawl: Stone Soup

    A game of dungeon exploration, combat and magic

    An open source roguelike adventure through dungeons filled with dangerous monsters in a quest to find the mystifyingly fabulous Orb of Zot. Crawl may seem easier than many other roguelikes at first glance, but dig a little deeper and you'll find it's just as challenging as some of the most difficult variations out there and a good deal harder than the rest. A strong set of design philosophies makes it much friendlier (and generally fairer) to the player - deaths are a learning experience instead of an exercise in frustration. Crawl also sports a number of systems and mechanics that diverge from more traditional roguelikes. For example, there's less emphasis on character classes (or backgrounds in Crawl parlance); your character is defined more by their skills, species and choice of deity than their background. Crawl includes an in-game tutorial and manual in the name of providing something playable without the aid of a guide or wiki.

    Defold

    Defold

    Free game engine for development of desktop, mobile, and web games

    Defold is an open-source, cross-platform game engine originally developed for 2D games but also capable of 3D — intended to give developers a turnkey solution for building games for desktop, mobile, web, and even consoles. It ships as a full editor/IDE, combining scene editing, asset management, scripting, and build/export pipelines, so developers don’t need to assemble disparate tools themselves. Game logic is written in Lua (with optional native extensions in C/C++ when needed), and the engine uses a component-based system and a message-passing paradigm to manage object interactions — a design that promotes loosely-coupled, reactive game code rather than traditional heavy OOP. Defold is optimized for efficiency: exported games tend to have small binary size and low memory use, making it appealing for mobile, HTML5/web, and lightweight games.
