Using text characters as your graphics was cutting edge in 1980. But with today's rendering capabilies and GPUs and bazzillions of colors who would go back to games like Rogue?
Well plenty of people apparently. Check out ADOM. Its a "Roguelike" still being made (started in 1992) and has quite a following.
As computers go, you don't get more retro than this. And if text adventures like Zork are the OD&D/Holmes or Cook/Moldvay, the Roguelikes would definately be the 1e AD&D/BECMI of computer gaming. Ultima 4-5 are the 2e, but in a good way, with Ultima 6 and 7 definately come in as 3.0 and 3.5 respectively and respecfully: even black Isle picked up their form factor. But Ultima 4 and 5 are video games that just say "RETRO" to me. And even now we are starting to see the Ultima-likes in things like the Nazghul toolset and the game Haxima.
So it is in the spirit of these games that I am creating Codex. Codex is shaping up to tip its hat to the roguelikes and ultimalikes as well as Judges Guild, OD&D, Holmes, C/M, BECMI (without the CMI) and even certain mechanical aspects of 1-4e. Think of Codex as a modern game created with retro sensibilities and front end, kind of like using tools that were designed for an Apple2 on a modern high end gaming PC that is equivalent to about 1000 Apple2s.
By the way- has anyone seen any Wizardrylikes?
