Contemporary games take place in something resembling the familiar, modern world.  They may be wholly based in a world with normal rules of reality or they may include elements of urban fantasy: occult magic, otherworldly deities, or supernatural creatures existing alongside normal humans.  There may also be differences from the "real" world in the level of technological advancement in a "what if?" situation.  Additionally, this category may include various RPoL- and roleplaying-related discussion boards and workshops.
