You know, honestly, I don't see the particular problem with winning a skill challenge in 3 if you're normally supposed to win it in 6, now that you mention it. But there were others posting in this thread who did see that as a problem and I guess I was responding to that.Lord Zardoz said:How is the "What if they Win it in 3" problem any different than "What if my players manage to defeat the epic final encounter I had planned within one round or less"?
In general, the consensus answer to most questions is that if it wont harm your game in the long term, then reward unexpected successes of that sort by just going with the flow.
In re improvising in general, there are really lots of little issues that go along with a heavier improvisational burden on the DM, not just catastrophic brain failure – things like falling into cliches ("oh great, Thog, you failed another History check; the DM's going to send a crow again to set off the trap") or whatever. I don't think the emphasis on improv is terrible, just something to keep an eye on. Carry on.
