"Crossfire is a multi-player graphical arcade and adventure game originally made for the X Windows systems environment. It has certain flavours from other games, especially gauntlet and the rogue-like games (Nethack, Moria, Angband, and Ragnarok). Any number of players can move around in their own window, finding and using items and battling monsters. They can choose to cooperate or compete in the same world.''In the years of development that have followed, Crossfire has grown to encompass over 150 monsters, about 3000 maps to explore, an elaborate magic system, over 15 character types, a system of skills, and many, many artifacts and treasures.

ZQuest Classic started as a classic 80s-style dungeon-crawler game engine, that over time has grown into a more modern engine. It allows much easier creation of dungeon-crawler style games than other big game engines, due to the number of features that are available without the need for any form of programming knowledge.

Muehle is a no frills implementation of the classical board game Nine Men's Morris. It does not have any cool features: no play against other humans (neither locally nor via the network), no play computer vs computer, no stats, no time control, no learning from play, no analysis mode, no variants for the rules of play. It's just to have some fun playing against the AI. The only additions: you can undo moves; and the AI will indicate when it thinks the position is dead even (you may take that as the AI offering a draw). You, on the other hand, cannot offer a draw: that would be pointless, as the AI is not designed to handle it anyway. Just quit or start a new game if you feel the current game is going nowhere.The AI uses a Monte Carlo tree search variation with a hand crafted evaluation function that is based on pattern counts (e.g., the number of open mills) and also has perfect knowledge of the game theoretic values of all 3 on 3 positions.Muehle is distributed free of charge and comes without any (not even implied) waranties. So don't use it. If you decide to use it anyway, you may find the annotated screenshot helpful.

Toy Mart has closed for the evening. The clerks have long since turned off the cash registers, and the midnight janitor has left. Suddenly the store comes alive as dolls, action figures, and game pieces jump to their feet. Within moments cities are formed: in the Bargain Bin, race tracks become islands of action surrounded by a sea of on-looking toy robots. In the Clown Department thousands of insane clowns initiate a massive pie fight. Throughout all of the departments, life arises...Suddenly there is a commotion in the Doll Department! One of the cages in the Stuffed Animal Zoo has broken open – hundreds of Fuzzy Bunnies hop out of the cage and scatter. The Fuzzy Bunnies, with their limited intellect, do not realize the danger they are in. The new metropolis of Toy Mart can be a very dangerous place for Fuzzy Bunnies to wander alone, and without help they stand little chance of surviving until morning.The peaceful inhabitants of the Doll Department cry out for the Fuzzy Bunnies to return...but to no avail. What will they do? What will become of the Fuzzy Bunnies?“I WILL HELP YOU!” storms a deep, resonant voice from one of the shelves. A hush crawls over the crowd of Fuzzy onlookers. A large package tumbles from the shelf onto the floor and bursts open...and a figure emerges. Yes, it's Mighty Mike – the most powerful action figure money can buy!About this port: Mighty Mike was initially released as a Mac exclusive under the name “Power Pete” by Pangea Software in 1995. This port aims to provide the best way to experience the game today. This port was made and re-released under permission from Pangea Software, Inc.

You are a lone adventurer in a strange, non-Euclidean world. Gather as much treasure as you can before the nasty monsters get you. Explore about 50 different lands, each with its own unique treasures, enemies, and terrain obstacles. Your quest is to find the legendary treasure, the Orbs of Yendor. Collect one of them to win! Or just ignore your quest and collect smaller treasures.The twist is the unique, unusual geometry of the world: it is one of just few games which takes place on the hyperbolic plane. Witness a grid composed of hexagons and heptagons, straight lines which seem to be parallel, but then they diverge and never cross, triangles whose angles add up to less than 180 degrees, how extremely unlikely is it to reach the same place twice due to practically infinite size of the world (centillions of locations in just 700 steps from the starting point), and how the world seems to be rotated when you do return. All this matters for the gameplay. The game is inspired by the roguelike genre (although in a very minimalist way), works of M. C. Escher, and by puzzle games such as Deadly Rooms of Death.

Porymap is a cross-platform map editor for the Gen 3 pret decompilation projects. Its primary functions are to allow editing map tiles, collision, events, connections, and properties. Porymap provides additional functionality, such as tileset editing and region map editing.
      Those familiar with traditional Gen 3 binary ROM hacking can think of it as the Advance Map equivalent for the decompilation projects. Porymap supports the same features as Advance Map, so Advance Map users shouldn’t have much difficulty learning how to use Porymap. There are many usability improvements in Porymap. The most notable is undo/redo when painting map tiles.
      Porymap reads and writes files in the decompilation projects. It does not read or write ROM files. Therefore, it is highly recommended to use Git for version control when working with Porymap.

      Depending on the game, users can randomize where items appear, how areas connect to each other, and more. And after things are changed, Randovania checks each randomized game to make sure it's beatable. Experienced players can also turn up the difficulty by making glitches and unintended tricks potentially required to win. (Randovania will not expect players to use glitches to win otherwise.)

Race Into Space is a simulation of the US-Soviet Space Race. In it, you take charge of your country’s space program as Director (US) or Designer (USSR). You will purchase and develop space hardware, recruit and manage astronauts/cosmonauts, and plan and send missions into space. The ultimate goal is to be the first to complete a Moon landing and return your people safely to Earth.Race Into Space (RIS) is a port to modern operating systems of Buzz Aldrin’s Race Into Space (BARIS), a DOS game originally released in 1993 on floppy disk, and a year later in an expanded CD version. BARIS was developed by Fritz Bronner based on his 1989 board game Liftoff!. Dr. Aldrin’s name and imagery have been dropped because permission to use them was limited to the old DOS game.RIS is available for Windows, Linux, and Mac, and includes some improvements over the original game—which we feel have justified a rewrite of the game manual. Those involved in RIS are volunteer enthusiasts, and we hope you enjoy this simulation. You might even find it educational.
