Bridge Over Troubled Water is a short adventure that I was able to complete in about an hour. Your party is tasked with delivering a message from Castle Hearkenwold to the Fortress of a Duke on the far side of a bridge. There is a lot of geography and politics which make you feel like you are seeing a small piece of a much larger world, but there is nothing that you are required to be familiar with ahead of time. Dorateen makes use of Question List events for all conversations with NPCs and hostile encounters. This is a clever idea that simulates the conversation trees from games such as Baldur's Gate, and it really helps to bring the setting to life.
I played with an average party that did not have all their stats maxed out. The combat was well-balanced, challenging, and not overwhelming. I cleared out the entire bridge area without resting, and accomplished the main task of delivering a letter to the Duke's Fortress. At this point, I was confused because not much seemed to happen, so I went back and re-explored the entire bridge area, finding a couple isolated encounters which I had missed the first time. Then, I went back to the fortress and discovered that you have to exit and re-enter the fortress once for each one of the quests that you complete. In retrospect, a better strategy would have been to make a bee-line to the fortress, where a Cleric can heal you, and then explore the bridge one encounter at a time, rather than clearing the entire area first. This module gives you the freedom to explore the bridge environs in any order you choose.
Well balanced encounters, a deep sense of history and geography, and engaging conversation chains made this an enjoyable way to spend an evening.
