That's not what we meant. Yes, the DM controls the people and creatures that are the player characters' adversaries, but that isn't the same as the DM being adversarial.
I guess you haven't had an adversarial DM yet, or you'd know what one is: Someone who screws the party over, counters everything they do, negates their strengths and attacks their weaknesses, tries to kill them while staying within the "rules".
Ahh, now I see.
No, I haven't had an adversarial DM (as you describe one) as of yet. The closest I've come is a story-type DM who tended to have us follow a planned general outline (although we could deviate a bit from it, to a degree). On the other hand, it was still quite a bit of fun as he tended to hand out LA templates and higher level items rather than levels / xp / etc. So I started at first level and ended a couple months later (real time) at 3rd level - but I was also a half-celestial hawk lycanthrope [controlled] with a minor artifact undead turning spear for a weapon. And the story line - though quite odd at times - was very interesting, involving multiple trips through time, the planes, etc.
I had another DM that played rough but fair with the rules. There were always several paths we could take, but occasionally he would throw out paths that weren't meant to be taken till several levels later - and wouldn't tell us, giving us only a few hints at best. If we took the wrong path, we might find ourselves easily overcome and having to retreat - often with one or more PC fatalities, as he would not have adjusted the plots for our current level. On the other hand, he warned us ahead of time of his style, and when it came time to choosing which paths to take, he tried to make certain that we had as much information as PCs of our level could possibly find / receive. If the path was made for a higher level it was harder to find info on it - usually our first clue that perhaps we should choose another. Over the course of about a year of real time (about three years, game time) I must have died about half a dozen times, but despite that when the campaign pettered out (it didn't really end, per se) I was an 11th level halfling bard. (I had been a ranger, a wizard, a rogue, and a fighter, prior.) So I was still able to advance, and the overall setting was quite interesting, having been built over years (real time) via decades (game time) of prior adventuring groups he had played with.
I haven't really had a DM 'out to get me' or the others in the game. I've had them play the foes using intelligent tactics and the weapons, armor, and items that might be expected of PC classed NPCs of their levels, but I consider that standard for the game.
