Knightly is quick to point out that gaming "a serious business".
"These are hi-tech, high-export jobs and the games industry is pioneering new business models."
He said 99 per cent of games developed in New Zealand are designed for international markets and exported.
The challenge to is help more Kiwi developers become more than one-hit-wonders, he said.
That could soon become more likely, with the Auckland Media Design School currently waiting on final NZQA approval to run two bachelor degrees, the Bachelor of Software Engineering (Game Programming) and Bachelor of Creative Technologies (Game Art). If approved, both would start this August.
Keynote speakers at tomorrow's conference are UK indie game developer Alex Amsel, and one of the industry's biggest publishers, Jeff Olsen, vice-president of Adult Swim Digital.
Kiwi speakers include developers from successful companies Grinding Gear Games, Cerebral Fix, Instinct, NinjaKiwi, Sidhe/PikPok and SmallWorlds.
The local industry's speedy growth is partly because game design and development lend themselves well to Kiwis, said SmallWorlds co-founder Mitch Olson.
"You need both smarts and creativity. Our solid education system, together with that number-eight wire mentality that Kiwis have, creates good conditions for game design in general terms," Olson said.
He said because capital costs are low - "all you need is a laptop" - and geographical distance is irrelevant because of the web, there are plenty of opportunities for Kiwis to make it in the industry.
Tickets to this year's conference sold out quickly, prompting the NZGDA to find a bigger venue and release a second round of tickets, which have also sold out.
