Yes, that's what I meant, thanks, and I was thinking particularly of the 2nd game - though on closer inspection I think UW2's walls are all only 45 degree and 90 degree just like the 1st game, except the UW2 map is higher res and a lot better at mixing them up so it's less obvious. So Doom does win there after all, but I didn't notice as a kid. Wolfenstein's are all 90 degree bends, I think.

Both Doom and UW2 were essentially still a 2d map but in UW2 I remember going down a descending corridor and swimming under a bridge I'd previously walked over and being amazed. There's another level full of aerial paths which cross over each other too, and a level where you flick a switch and flood the map and open up some walkways above the flooded area iirc. I don't know how it represented these over-under areas internally but even if no more 2d than Doom (though you could look up and down a bit) it was a nice trick.

Then again, Doom has similar tricks - teleports set up to act like lifts, where the top of the tower looks out apparently over where you've already been (actually a facsimile to get round the 2d addressing).

But yes, Doom did win out for speed and sheer frantic joy/terror. I couldn't convert any friends to Ultima but Doom won everyone who saw it over instantly...
