- Iceutils false

- Junk Lab false
- This is a candidate for deletion: Links broken. No archive.org entry. Email to maintainer broken. Poppy-one (talk) 13:28, 6 August 2018 (EDT) It's a dungeon exploration game. You are a niece of an extraordinarily eccentric mad scientist. You come to visit him in your blimp in his huge underground lab, when you notice that the lab is devastated, all the specimens are running lose, the staff has been turned into mutant zombies, and the robots are trying to exterminate everything in sight. Somebody needs to stop this by getting to the lowest levels of the lab and aborting whatever weird experiment has gone awry. On the way down you collect nifty lab equipment and parts for your portable doomsday machine. The game is not playable yet, although you can walk around a predefined map and hit some monsters. As it's a hobby on the side, it might take a while to finish.

- Nethack false
- Single player adventure game (similar to Rogue) of dungeon exploration that runs on a wide variety of computer systems, with a variety of graphical and text interfaces all using the same game engine.

Each game presents a different landscape - the random number generator provides an essentially unlimited number of variations of the dungeon and its denizens to be discovered by the player in one of a number of characters: you can pick your race, role, and gender.
- OHRRPGCE false
- The Official Hamster Republic Role Playing Game Construction Engine (OHRRPGCE, usually abbreviated to OHR) is a cross-platform (GNU/Linux, Windows, Mac, BSD, Android) easy to use game creation engine for 2D role-playing games (RPGs) similar to the classic Final Fantasy. No programming is required to create a game, though there is a custom scripting language called HamsterSpeak which has been used to create numerous non-RPG games including side-scrollers/platformers, rogue-likes, arcade games, puzzle games and more. The OHRRPGCE has been in active development and had an active community for over 20 years, with over 1600 games available for download, plus a few commercial ones. Unlike other game engines, backwards compatibility is maintained with all previous versions ever released. It has been free software since 2005, whereupon it was ported from QuickBASIC (and MS DOS) to FreeBASIC and given new life. The community is centred around the Slime Salad forums and gamelist.

It is written in Java by the Arianne Project, which was awarded project of the month March 2010 by SourceForge. Stendhal is a fun friendly and free multiplayer online adventure game. Start playing, get hooked... Get the source code, and add your own ideas... Stendhal has a huge and rich world. You can explore cities, forest, mountains, mines, plains, caves and dungeons. You could meet over 250 NPCs, many will give you tasks and quests for valuable experience, shiny gold, but mainly a warm fuzzy feeling. Your character will develop and grow and with each new level up become stronger and better. With the money you acquire you can buy new items and improve your armour and weapons, trade with friends, or look for what other players are giving away in the 'community chest'. If you just want to fight that helps too - the cities could get overrun by monsters without you! So what are you waiting for?! A whole new world awaits...
