Marvel: Contest of Champions, in which stronger and rarer characters are marked with more stars to make them appear more valuable. Stars are also used to rank a game or stage's difficulty (such as in the SNES version of Street Fighter II and its updates), or to rate the attributes of a selectable character or, in sports games, a team. Restaurant ratings Restaurant guides and reviewers often use stars in restaurant ratings. The Michelin system reserves star for exceptional restaurants, and gives up to three; the vast majority of recommended restaurants have no star at all. Other guides now use up to four or five stars, with one-star being the lowest rating. The stars are sometimes replaced by symbols such as a fork or spoon. Some guides use separate scales for food, service, ambiance, and even noise level. The Michelin system remains the best known star system. A single star denotes "a very good restaurant in its category", two stars "excellent cooking, worth a detour", and three stars, "exceptional cuisine, worth a special journey". Michelin stars are awarded only for the quality of food and wine; the luxury level of the restaurant is rated separately, using a scale of one ("quite comfortable") to five ("luxury in the traditional style") crossed fork and spoon symbols. Hotel ratings Hotel luxury is often denoted by stars. Other classifiers, such as the AAA Five Diamond Award, use diamonds instead of stars to express hotel rating levels. Hotels are assessed in traditional systems and rest heavily on the facilities provided. Some consider this disadvantageous to smaller hotels whose quality of accommodation could fall into one class but the lack of an item such as an elevator would prevent it from reaching a higher categorization. In recent years hotel rating systems have also been criticized by some who argue that the rating criteria for such systems are overly complex and difficult for laymen to understand. It has been suggested that the lack of a unified global system for rating hotels may also undermine the usability of such schemes.

Defaqto is an organization that independently assesses every financial product in the UK.
