Hussar said:Essentially, I got caught not doing my prep. In a high level game, you can't do that. At low levels, you can wing it and have a pretty decent chance of getting it right. High level doesn't have that flexibility. There are just too many variables.
I don't want running a game to be hard work, at any level. High level 1e was easy. High level 3e is tough and challenging to run; I have had very similar experiences to the one you had with the WLD. Although the common alternative high level bad experience of a TPK isn't fun either. Unlike you, I don't see it as a fault with me and my GMing skills, but with the ruleset. Hence I'm using C&C in future, which like 1e does not have much inherent increase in complexity by level, and in which, like 1e, it's not seen as some kind of failed encounter* when the 13th level PCs wipe out the 300 mooks.
*I'm not certain why this is, but I think it's to do with the amount of time 3e takes to set up an encounter, and the implications of the CR/EL system. I recall running 3e ca 13th level, we once took about 4 hours, an entire session, to resolve a battle between the PC party and a force of around 60 low-level Duergar (this was a converted 1e adventure). The battle was vaguely interesting, but took far far too long, and the PCs were never seriously threatened. In 1e the Duergar would all have been dead in a few minutes of real-time and we could have got on with the adventure.
