From the review:
Tabletop gaming can be a very expensive enterprise. Your typical tactical wargame consists of a large box packed with models, rules and counters and tends to cost about the same as two or three newly released video games. Such an enterprise can make it difficult for the smaller games companies to get much of a foothold, because all of that costs a lot of cash to set up and it also puts off the more casual sort of gamer. Luckily there is a way smaller firms can write great games and at the same time offer these things for pocket money prices.
