The Interactive Games & Entertainment Association has called the resignation of Australian senator and games advocate Scott Ludlam "devastating".
Ludlam, a senator and deputy leader for Australian Greens party, resigned last week after it emerged that he holds dual citizenship with New Zealand, a breach of the constitution that rendered his re-election invalid.
"Scott Ludlam was undoubtedly the biggest advocate for the video games development industry in Australia," said the IDGA in a statement.
"His effort and relentlessness was second-to-none. At every opportunity possible, he always strived to support the industry.
"From pushing a Senate inquiry into video game development, to keeping the Government accountable for its late response to the report, to liaising and speaking with stakeholders on a frequent basis, he wanted nothing more to see the industry prosper in Australia."
It will be more difficult for the games industry to get Federal Government support and recognition without Ludlam, the IDGA said.
"We thank Senator Scott Ludlam for paving the way and laying the foundation of getting games on the Federal agenda," the statement continued.
"Your scrupulous advocacy and support will never be forgotten. We are sure we have not seen the last of you, we’ve noticed the job offers already. We cannot wait to see where you will kick ass next."
Ludlam described the citizenship mistake as an "avoidable oversight" that was "entirely my responsibility".
"It wasn’t the way I was hoping to go out," he told reporters on Friday. "There is an enormous amount of work left undone."
