"Space Invaders" first hit gaming arcades in 1978, setting players the challenge of shooting a swarm of hostile extraterrestials descending at an ever increasing pace - before they destroyed you. The hugely popular game, released a year after the "Star Wars" movie, was
"revolutionary," according to organizers of the Leipzig GC Games Convention, which starts on Wednesday.
"This might appear a simple feature to a modern audience but ... from then on, you didn't only play against the machine but also against human opponents," the organizers said in a statement detailing their homage to the game that in their view changed the nature of video games for ever.
"Space Invaders" though is not the main reason why some 200,000 people are expected to make the journey to the convention in the east German city of Leipzig between August 21 and August 24.
Held for the seventh time in Leipzig, 200 kilometres (125 miles) southwest of Berlin, the GC has exhibitors from more than 40 countries, including all the big names in the industry, except Nintendo, in four halls and an outdoor area.
According to the German tech industry association Bitkom, gamers in Germany alone are expected to spend €2.6 billion ($3.8 billion) on consoles and games this year, 13 percent more than in 2007.
"Today the games market ... is at least as important as other branches of the entertainment sector like film or music. With one difference: the games market is booming," Bitkom said ahead of the convention.
And in Germany at least, the games industry is slowly gaining respect, making it out of teenagers' bedrooms and overcoming criticism for being too violent to win widespread popularity.
Only last week, the German Cultural Council deigned to allow the country's games development association GAME to become a member, thereby officially making the industry part of the country's mainstream cultural establishment.
German MPs have even decided to create a special "Oscars" awards for video games, with 10 categories and 600,000 euros worth of prizes, starting in 2009. "Of course some games are bloody and they should not be in the hands of children. But that does nothing to change their aesthetic qualities," the Council's head, Olaf Zimmermann, told AFP.
The "Grand Theft Auto" series, which has sold about 70 million copies worldwide, is the most notorious, coming under fire for its graphic depiction of casual violence, drug dealing and prostitution. But its latest installment has also been heralded at the greatest video game of all time, with a great narrative and artistic merit.
