The Lost Vikings (1993), Age of Mythology (2002), and For Honor (2017). All three Vikings from The Lost Vikings series—Erik the Swift, Baleog the Fierce, and Olaf the Stout—appeared as a playable hero in the crossover title Heroes of the Storm (2015). The Elder Scrolls V: Skyrim (2011) is an action role-playing video game heavily inspired by Viking culture. Vikings are the lead focus of the 2020 video game Assassin's Creed Valhalla, which is set in 873 AD, and recounts an alternative history of the Viking invasion of Britain. Modern reconstructions of Viking mythology have shown a persistent influence in late 20th- and early 21st-century popular culture in some countries, inspiring comics, movies, television series, role-playing games, computer games, and music, including Viking metal, a subgenre of heavy metal music. Since the 1960s, there has been rising enthusiasm for historical reenactment. While the earliest groups had little claim for historical accuracy, the seriousness and accuracy of reenactors has increased. The largest such groups include The Vikings and Regia Anglorum, though many smaller groups exist in Europe, North America, New Zealand, and Australia. Many reenactor groups participate in live-steel combat, and a few have Viking-style ships or boats. The Minnesota Vikings of the National Football League are so-named owing to the large Scandinavian population in the US state of Minnesota. During the banking boom of the first decade of the twenty-first century, Icelandic financiers came to be styled as útrásarvíkingar (roughly 'raiding Vikings'). Experimental archaeology Experimental archaeology of the Viking Age is a flourishing branch and several places have been dedicated to this technique, such as Jorvik Viking Centre in the United Kingdom, Sagnlandet Lejre and in Denmark, Foteviken Museum in Sweden or Lofotr Viking Museum in Norway. Viking-age reenactors have undertaken experimental activities such as iron smelting and forging using Norse techniques at Norstead in Newfoundland for example. On 1 July 2007, the reconstructed Viking ship Skuldelev 2, renamed Sea Stallion, began a journey from Roskilde to Dublin. The remains of that ship and four others were discovered during a 1962 excavation in the Roskilde Fjord. Tree-ring analysis has shown the ship was built of oak in the vicinity of Dublin in about 1042. Seventy multi-national crew members sailed the ship back to its home, and Sea Stallion arrived outside Dublin's Custom House on 14 August 2007. The purpose of the voyage was to test and document the seaworthiness, speed,
