Rogue is an early PC RPG. It was done in ASCII, and runs on DOS, but it's very unrestricted in what you can do. Not that I ever had a chance to play it, had XP before I even heard of it, but you can find Nethack(freeware) if you want to try something similar. This one(Shiren) seems a better alternative for many though as, for one thing, it has graphics. Actually, I can think of another console game that could be considered a Rogue-like, Fatal Labyrinth for the Genesis.
Anyhow, my first time through, I got killed at maybe the 7th or 8th area(the pass they mention in the first town) by a confusion trap and a leveled up monster (ghost possession) with a katana +2. It's kind of irritating how you have to start at the very beginning at level 1 with nothing.
