My first CRPG was
Questron.
I loved Questron. I spent many hundreds of hours playing it. It was the sort of game where you got dropped in a world without any indication of what you were supposed to do. Once you'd travelled around a bit and gained a level, you'd receive a message from townspeople that "Mesron wants to see you". There was some lore in the manual that told you who Mesron was, and that he was in the castle, but the game didn't provide a map, so finding that castle took quite a while.
And then, once I was in the castle, my first character actually starved to death wandering its halls looking for Mesron.
And, while there was a map of the world available in the castle (it was a tiled floor, so you couldn't take it with you - you had to copy it yourself or memorise it), that map was actually inaccurate. The in-game cartographers had made entirely realistic errors much like those found in real medieval maps.
In hindsight, the game was terribly derivative of games like Ultima that had come before it (in fact, the original Questron box - which I still have - specifically thanks Lord British for licensing the game structure), but I have very fond memories of it.
I've never managed to make in work in a C=64 emulator, though.
