Just bought it and am printing bits out - lots of fun putting it together. The only downside is that the margins might be too narrow for some printers - but since all the pages fill the same width page "scaling" will be uniform across the pack, i.e. the grid will still match up. Naturally there's a lot of black ink involved, but the final effect is worth it, also you get to save on colour cartridges! The scenario is larger than expected: 20 pages of Pathfinder compatible adventure (will also work with D&D 3.5). The counters are a nice optional touch - some with art, many blank - with a 2D counters bag as well.
Just add some 6th-7th level characters and Pathfinder (or d20/D&D 3-3.5) rules and you have a complete immersive tabletop gaming experience, similar to any "out of the box" game currently on sale.
Re: Mini Review: The Trouble Brewing at Witchcliff - Game Pack (floor plan and scenario)
I know what you mean. There is a slight flaw in this set, if you have a big preference on style, as some of the furniture is very reminiscent of house plan technical drawing clip-art found on Apple Macs in the 80s - some of the seats are just too perfect geometrically.
0one Games have adopted an interesting niche, they sell plans which print in blue ink - which was the adopted colour of the inside cover maps in the TSR modules 70s-80s. Nostalgia is powerful thing.
It's a nice set though, good value. Putting together only part of the floor plan is very satisfying.
