Ok, Narf I'll set the record straight and give you a history lesson at the same time..
The origins of Rogue...
Michael Toy and Glenn Wichman, two students in University of Santa Cruz, California, experimented with curses library. They both had enjoyed playing Adventure which was the first text adventure game. After making some simple games with curses, they began to write a graphical adventure game. Michael Toy did most of the programming and Glenn contributed ideas to the project and coined the name "Rogue".
One of their main goals to create a game they could enjoy playing by themselves. Most existing adventure-type games had predesigned plot and world which remained exactly the same every time you played it. Michael and Glenn decided to make Rogue more random. Rogue build the dungeon using the pseudo-random number generator, so the game was different every time you played it, making it possible that even the creators of the game could be surprised by it.
So if you notice the bold text
"they began to write a graphical adventure game." you can see that the original rogue was indeed designed to be a 'graphical adventure' the fact that it uses 'curses' instead of bitmaps does not make it 'less-graphical'. They were simply using the tools of the day. (and making very innovative use of the tools too.)
What does this mean? It means that the original 'Rogue' was always meant to be a 'graphical' game and therefore all 'Roguelike' games should also be considered 'graphical' and weather they use 'ascii' or 'tiles' , has no bearing on their being roguelike. What makes games roguelike is 'Random' dungeons, treasure, monsters, multiple levels and a hot concept called 'replayability'.
Rogue is the 'Grandfather of crpg'. Give Rogue the full credit it is due. Don't just say it's the first text-based crpg, it is so much more than that.
I rest my case.
So what do I win?
Cheers!
