finer details can be included. For these higher levels of detail, plastic models have become more popular for higher standards of painting, as well as plastic models being less susceptible to flashing or casting imperfections and requiring less preparations before painting. Plastic models also allow for more options in the pose of the models as they are often sold on the sprue in pieces to be assembled, rather than a single piece of cast material. This allows for the kit to include multiple parts, as plastic is significantly cheaper than metal, that can fit together to allow multiple different variations of the model to be built, for example a kit might provide multiple different weapon options. Despite this, metal models are still widely and commonly available as plastic casting is more cost prohibitive for smaller manufacturers. The plastic casting process is cheaper for mass production, but expensive on a small scale as the steel molds are expensive to produce and maintain, so whilst many larger manufacturers have moved from metal to plastic, many smaller manufacturers continue to use metal. Models are also sometimes cast in polyurethane resins. Resin shares some of the advantages as plastics over metals. They are lighter, so can make larger models, can cast higher levels of details, and will often require less preparation before painting than metals. This makes resin a common choice for smaller manufacturers of larger scale models with high levels of details intended for display or competition painting, where resin casts can match the details of plastic models whilst still being affordable for smaller production lines. However, resins are often more brittle than plastics, with small details likely to break so, whilst smaller scale resin models are still produced where the productions are small, plastics are still favored by most manufacturers for smaller and mass-produced models. Genre, subject and style Models are produced in almost every genre. Due to the prominent links of production to miniature wargames the most common genres that models are made in are fantasy, sci-fi, and historical/military. The connection to wargames also means that a majority of models available are single characters (sold individually or in unit sets) in offensive or defensive poses. Within the broad genres, there is still large variation in the models produced by different manufacturers or even by the same manufacturer in different lines. For example, Games Workshop produces models for Age of Sigmar and
