Magic: The Gathering core sets, 1993–2007

The collectible card game Magic: The Gathering published nine core sets from 1993–2007, also referred to as basic sets and base sets. These sets consisted entirely of reprints, usually focusing on staple cards Wizards of the Coast felt should always be available. These cards were generally simpler than cards in expansion sets, omitting multicolored cards, and all but the simplest mechanics such as Flying, Trample and Haste. As Magic grew, the base sets were considered descendants of the original Limited Edition, and shaped the default setting and feel of Magic. In contrast, Magic "expansion sets" usually chose a particular theme, such as artifacts for Antiquities. All cards were given a white border to mark them as reprints, with a few exceptions (Tenth Edition, foil cards in Seventh-Ninth Editions). From Fourth Edition in 1995 onward, a new base set would come out once per two years in the spring or early summer; for tournament play, that set would be legal for two years in the Standard format until the next core set replaced it.

Dungeons & Dragons

Dungeons & Dragons (abbreviated as D&D or DnD) is a fantasy tabletop role-playing game (RPG) originally designed by Gary Gygax and Dave Arneson, and first published in 1974 by Tactical Studies Rules, Inc. (TSR). The game has been published by Wizards of the Coast (now a subsidiary of Hasbro) since 1997. It was derived from miniature wargames with a variation of the Chainmail game serving as the initial rule system.D&D's publication is commonly recognized as the beginning of modern role-playing games and the role-playing game industry.

D&D departs from traditional wargaming and assigns each player a specific character to play instead of a military formation. These characters embark upon imaginary adventures within a fantasy setting. A Dungeon Master serves as the game's referee and storyteller, while also maintaining the setting in which the adventures occur and playing the role of the inhabitants. The characters form a party that interacts with the setting's inhabitants (and each other). Together they solve dilemmas, engage in battles and gather treasure and knowledge. In the process the characters earn experience points to become increasingly powerful over a series of sessions.

Trademark

A trademark, trade mark, or trade-mark is a recognizable sign, design, or expression which identifies products or services of a particular source from those of others, although trademarks used to identify services are usually called service marks. The trademark owner can be an individual, business organization, or any legal entity. A trademark may be located on a package, a label, a voucher, or on the product itself. For the sake of corporate identity, trademarks are being displayed on company buildings.

Usage

A trademark identifies the brand owner of a particular product or service. Trademarks can be licensed to others; for example, Bullyland obtained a license to produce Smurf figurines; the Lego Group purchased a license from Lucasfilm in order to be allowed to launch Lego Star Wars; TT Toys Toys is a manufacturer of licensed ride-on replica cars for children. The unauthorized usage of trademarks by producing and trading counterfeit consumer goods is known as brand piracy.

The owner of a trademark may pursue legal action against trademark infringement. Most countries require formal registration of a trademark as a precondition for pursuing this type of action. The United States, Canada and other countries also recognize common law trademark rights, which means action can be taken to protect an unregistered trademark if it is in use. Still common law trademarks offer the holder in general less legal protection than registered trademarks.
