None of those. It's not a text adventure. It has graphics although a bit crude.
The game was mind-blowing at the time because you could travel around wherever you wanted on foot, by horse, or even own a ship. You could go into towns and the NPCs there were moving around doing stuff instead of just a guy behind a counter that you bought stuff from. And there was no pressing main quest like a big bad boss villain to beat. There was a quest but it was more a personal journey of growth than anything material and you could take your time with it if you wanted or just not do it at all and simply live in the world.
Many say that this game was the moment when computer RPGs grew up.
In fact it might have been too grown-up for its time as the series soon returned to the usual formula of find-and-kill-the-all-powerful-baddie after this one. I guess players just didn't know what to make of so much freedom. I loved it to death and played many, many times: This time I'll be a hunter and live off the land. This time I'll be a pirate sailing the seas for plunder. This time I'll be a cold-blooded killer. This time I'll master all the magic systems. This time I'll be... etc. etc.
I guess it was one of the first games where the player could set and achieve their own goals instead of the game deciding them for you.
