I can assure you that we use the regular B/X combat procedure, and that combats in our game last for several rounds; though I can affirm that 40 seconds is probably not that far off for some of their turns. "Description" for some of 'em = "I swing my sword, hit AC X, do X damage...NEXT!"
Combat happens, of course, but it's not the point of, nor even a primary feature of, our games. They prefer figuring their way out of traps, puzzles, etc. One of the more time consuming sessions involved their finding a scroll written in the goblin tongue (in other words, transposed into a random runic font from my computer). None of them spoke goblin, so I didn't provide a translation. They found the scroll about 20 minutes into the game, and rather than taking it back to town to have it translated (as I'd intended), spent the rest of the session comparing symbols with commonly-used letters in English (Common) and translating it themselves.
I also haven't seen much in the way of combat 'slow-down' by spellcasters, simply because only one PC (an elf) casts spells at all, and she doesn't use her spells all that often; and since magic isn't a huge interest for the players, I only rarely throw magic-using foes at them.
In that respect, my game is probably an anomaly.
Well, that certainly is another option for speeding up turns in combat - strip out every option available other than, "I attack once" or, "I cast magic missile". :/
I mean, come on. I can take turns in Monopoly pretty quickly too, but, that doesn't make Monopoly better than Go. Different yes, but not better. B/X combat has pretty much no options - no summoning, few if any buffs, 1 attack per round, no feats or variable adjustments and no attacks of opportunity.
Sure, it's faster, but, that hardly makes it better.
But, back OT. I've never hit the 15 minute round either. But I've certainly hit the 10 minute round. It just takes time. I find it very difficult to believe Bullgrit's story that his friend is dealing with multiple trip attempts (because that requires TWO rolls - the DM better be on the ball as well), spells and his own personal attacks in under a minute and a half. I'm sorry, I flat out do not believe that.
But, remember too, he's only summoning wolves who have one attack each. Summon creatures with multiple attacks, or attacks that force saving throws and watch the speeds drag. Or, perhaps Bullgrit never moves his opponents so they never draw AOO's, thus dragging turns on even longer.
Bullgrit, I do agree that the 15 minute turn is probably hyperbole. However, OTOH, I do not believe that you are being accurate when you say that the druid player is doing all that in 90 seconds consistantly. Perhaps if his turn goes exactly as planned, his wolves draw no aoo's, and everybody is paying 100% attention, the stars and the moon line up just exactly, then you might get that. Regularly? If true, that's bloody impressive.
