In 2003, he produced the first live orchestra performance of video game music outside Japan at the Gewandhaus in Leipzig,[4] Germany, which led to his international series Game Concerts,[5][6][7] including the Final Symphony world tour from 2013, the first performance of video game music by the London Symphony Orchestra,[8] and from 2021 the symphonic fairy tale Merregnon: Land of Silence, premiered by the Royal Stockholm Philharmonic Orchestra.

During the 80s, his father was allowed to travel to the western part of Germany to visit his own mother and brought back a Commodore 64 for the family.

[2] Soon enough, he developed a passion for video game music and became especially fond of Chris Huelsbeck’s works on the Turrican series.

[15] Following the success of the event, further four annual concerts with various programmes took place under his direction until 2007, performed by the FILMharmonic Orchestra Prague.

A large number of composers took part in the events and the associated autograph sessions, including Nobuo Uematsu, Yuzo Koshiro, Chris Huelsbeck, Rob Hubbard and Allister Brimble.

[27] The programme subsequently toured the world with performances in Japan, Denmark, Sweden, Finland, the Netherlands, the USA, New Zealand, China, Austria and Australia.

[28] The world premiere of Final Symphony II, featuring music from Final Fantasy V, VIII, IX and XIII, took place on 29 August 2015 at the Beethovenhalle in Bonn, Germany, performed by the Beethoven Orchester Bonn, followed by four performances in September and October 2015 by the London Symphony Orchestra in London, Osaka and twice in Yokohama.

[29][30] In addition to events in Germany, the UK and Japan, Final Symphony II was also presented in Finland, Sweden and the Netherlands.

[35] Böcker produced another concert film in September 2023, again for Bethesda Softworks, for the action role-playing game Starfield, which had just been released at the time.

It was produced by Thomas Böcker to introduce young people and families to orchestral music in the tradition of Sergei Prokofiev's Peter and the Wolf, with modern means adopting a game and anime aesthetic.

In an interview with ZEIT, Nobuo Uematsu confirmed that he would no longer compose music for entire video games in the future, and would instead focus on other projects that he loves, such as Merregnon: Heart of Ice.
