Return to Castle Wolfenstein is a re-imagining of id Software‘s classic Wolfenstein 3D, developed by Gray Matter Studios and first published by Activision in 2001. It uses the id Tech 3 engine (as created for Quake III) and has a single-player campaign, as well as a multiplayer component where players are split into Allies and Axis.
Duke Nukem Forever is the long-awaited sequel to Duke Nukem 3D that was in “development hell” for over a decade and was finally released in 2011. It was developed by 3D Realms and Gearbox Software (with contributions from Triptych Games and Piranha Games) and published by Take-Two Interactive. The game is a first-person shooter that satirises all-American action heroes, with over-the-top weapons, giant explosions, and puerile humour. Jon St. John once again returns to voice Duke himself.
Duke Nukem 3D is an infamous first-person shooter, developed and published by 3D Realms in 1996. It is the sequel to the platform games Duke Nukem and Duke Nukem II, which were released in 1991 and 1993 respectively, and it is arguably the biggest-selling and most popular game in the Duke Nukem series.
The first Duke Nukem game is a simple side-scrolling platform shooter, developed and published for PC MS-DOS by Apogee Software in 1991.
Jazz Jackrabbit 2: The Christmas Chronicles is an enhanced version of Holiday Hare ’98 and was developed by Epic [Mega]Games and published by Project Two Interactive in 2000. It apparently only saw a limited release initially, due to the publisher going out of business, but it has since been re-released on GOG.com as part of the Jazz Jackrabbit 2 Collection.
Ultima IX: Ascension is the ninth and final instalment of the core Ultima series and was developed by Origin Systems and published for Windows-based PCs by Electronic Arts in 1999. It was the first Ultima game to use polygonal rendering in a full 3D environment.
Ultima VIII: Pagan is the eighth entry in the Ultima series and was developed and published by Origin Systems for PC MS-DOS in 1994. Like its predecessor (The Black Gate), Pagan goes for a darker, more mature tone than most of the previous Ultima games, and it is also more puzzle and action-oriented.
Serpent Isle is an oddity in the Ultima series in that it is a direct sequel to the previous game – Ultima VII: The Black Gate – which uses the same game engine, but with a few enhancements. It was published by Origin Systems in 1993 and only ever appeared on the PC, running under MS-DOS.
