Warhammer 40,000 – One of the most daunting things about starting this hobby is having to put together your models. (Painting is a close second, since before you can do that you need to put them together.) This is especially true for newer players that are interested in the social and tactical aspects of tabletop gaming but come from a background of video or board games where everything is ready to go right out of the box. A large percentage of these newer gamers don't have an interest in the hobby aspect of the game (yet, it will come with time) so paying to have these parts taken care of makes sense for them.
