Super Mario Bros. (スーパーマリオブラザーズ Sūpā Mario Burazāzu?) is a 1985 platform video game developed by Nintendo, published for the Nintendo Entertainment System as a pseudo-sequel to the 1983 game Mario Bros. It is the first of the Super Mario series of games. In Super Mario Bros., the player controls Mario and in a two-player game, a second player controls Mario’s brother Luigi as he travels through the Mushroom Kingdom in order to rescue Princess Toadstool from the antagonist Bowser.
The success of Super Mario Bros. has caused it to be ported to almost every one of Nintendo’s major gaming consoles. Nintendo released special red variants of the Wii and Nintendo DSi XL consoles in re-packaged, Mario-themed, limited edition bundles in late 2010 as part of the 25th anniversary of the game’s release. In 2005, IGN‘s poll named it as The Greatest Game Of All Time.

Tecmo Koei Holdings Co., Ltd. (Japanese：コーエーテクモホールディングス株式会社, Kōē Tekumo Hōrudingusu Kabushiki-gaisha), is a holding company created in 2009 by the merger of Japanese video game developers and publishers Koei and Tecmo.
Koei Europe changed its name to Tecmo Koei Europe, Ltd and now releases video games under the new moniker. In January 2010, Tecmo, Inc. and Koei Corporation merged into Tecmo Koei America Corporation. Tecmo has been declared disbanded in Japan, effective as of April 1, 2010. Koei Canada, Inc. has since changed its name to Tecmo Koei Canada, Inc.
The continued operating loss prompted Kenji Matsubara, the former president and CEO of both Tecmo Koei Holdings and Tecmo Koei Games label to tendered his resignation in November 2010. Yoichi Erikawa – Co-founder of Koei – will take over the four positions vacated by Kenji Matsubara.
Koei Co., Ltd. is a Japanese video game publisher, developer, and distributor founded in 1978. The company is best known for its historical simulation games based on the novel Romance of the Three Kingdoms, as well as simulation games based on pseudo-historical events.
The company has also found mainstream success in a series of loosely historical action games, the flagship titles of which are Dynasty Warriors (真・三國無双 (Shin-Sangoku Musō)) and Samurai Warriors (戦国無双 (Sengoku Musō)), the Musō (無双) series. Koei also owned a division known as Ruby Party, which focuses in dating sim games.
On April 1, 2009, Koei merged with Tecmo to form the Tecmo Koei Holdings holding company.  Koei changed its name to Tecmo Koei Games on April 1, 2010 by absorbing Tecmo. Tecmo Koei Games continues to use the Koei brand.
Studio acquisition and management practices
During its period of fastest growth, EA was often criticized for buying smaller development studios primarily for their intellectual property assets, and then producing drastically changed games of their franchises. For example, Origin-produced Ultima VIII: Pagan and Ultima IX: Ascension were developed quickly under EA’s ownership, over the protests of Ultima creator Richard Garriott, and these two are widely considered to be subpar compared to the rest of the series.
In early 2008, current CEO John Riccitiello acknowledged that this practice by EA was wrong and that the company now gives acquired studios greater autonomy without “meddling” in their corporate culture.
