4 out of 5 rating for Raiders of the Twilight Marsh
Played at winter fantasy with 3 members of my gaming group, but we had decidedly different experiences as we had to split up among different tables. Since they will not be reviewing it, this rating will reflect the compound view of our experiences.
This is a pretty straightforward scenario, ending as you might expect given the description. That said, it is very well-written, and includes several fun fights and a great role playing opportunity that directly impacts how the rest of the scenario plays itself out. Unfortunately my table and I made all of the wrong choices, and as a result were unable to complete the adventure with a somewhat poorly balanced party of 6 level 5-6 characters. Although the end result was disappointing, it did make sense in the context of the choices we made so I cannot really fault the author (DM could have been a bit more helpful, but was certainly fair).
My friends made better choices and had more optimized tables, and had truly epic (and successful) final battles. I was quite jealous when we debriefed at the end.
As a result of my experiences I'd rate the scenario a 4, but my friends would call it a 5. Notwithstanding my own frustrations, this is an adventure I would recommend for all.
