In fact, all of the Ultimas through V had first-person dungeon views.
Wizardry's wireframe dungeon renderer was a bit more advanced, though, in the sense that it supported empty space and disjoint 'islands' in the map, while Ultima I and II could only display corridors.
IIRC that limitation was fixed by III, but it may have been IV. It was definitely fixed by V.
I dunno about Ultima III, but QotA had 'battle screen' sections of dungeon, which basically means a top-down section. I believe the altars are in such sections? I do know there's a three-way split in the Stygian Abyss, because I accidentally went around in a circle last time I played.
QotA is really awesome, I should play it again some time.
It had both top-down 'combat rooms' and a 3D first-person view (as did Ultima III.)
Of course, in Ultima III, you couldn't leave the top-down combat arena until the monsters were dead or you were. That was also fixed in Ultima IV, where you could chicken out at the cost of some Valor.
