The rise of free-to-play mobile games has provided a great opening for Flash developers.
Structured around a model of releasing a lot of free and very engaging web games, they've built up strong communities of highly committed players.
And the ability to move beyond a pure advertising business model to one that includes in-app purchases has clear opportunities in terms of boosting average revenue per user.
Friction in the system
But, of course, there have been challenges too.
Developing native games that are distributed through app stores is technically very different to building Flash games on the open web.
There are also restrictions in terms of updating content. On the web, you can do anything, anytime, whereas iOS requires at least a week wait for Apple approval.
These are the sort of issues that have been bedevilling Adam Bohn.
The self-styled "world's friendliest and craziest video game creator" and CEO of Artix Entertainment, Bohn - who also goes under the moniker Artix von Krieger - clearly loves the freedom that the web enables. That's one of the reasons that Artix has been relatively slow onto mobile.
Its debut - a symbol-matching RPG called Battle Gems - was only released on iOS in March.
"It was supposed to be a quick two months project, but ended up at eight months," Bohn confesses.
That's what happens when you're building game that's looks to differentiate itself with "massive character customisation".
"We planned 256 levels because it's the square root of my favourite number - 65,536. But we ended up with over 480," Bohn reveals, of the scale of content creep that comes from caring passionately about the games you're making.
"Sure, you can shotgun a bunch of low quality games," he says. "If you want to fail.
"We want to bring to mobile what we have on the web; that's giant dynamic worlds we update constantly."
Back to battle
To that degree, Battle Gems is a proof of concept for Bohn's bigger plans, which revolve around Artix's signature game AdventureQuest Worlds.
First released in 2008, Bohn says the Flash-based MMORPG was way ahead of its time.
Indeed, the game was so successful - over 100 million registers users to-date - he turned down a $84 million acquisition deal.
You can shotgun a bunch of low quality games ... If you want to fail.
"Then we started making flops," he says, with jokey regret.
AdventureQuest Worlds 2 is designed to change that situation.
It's being developed, and will initially launch, on web, with iOS and Android versions being working on concurrently, albeit with a delayed release schedule.
"The future is omni-gaming," Bohn explains. "The game will be everywhere but the web version will have more complicated and richer features."
Rules of the game
It's the approach that best reflects Artix's history and expertise.
"We have a large and loyal audience on the web, but mobile is still a strange beast to us," Bohn confesses.
He says he's been encouraged by the reaction Battle Gems has received, though.
"There's been so much genuine love from the fans and we've had 300,000 installs without any marketing."
Yet, perhaps the biggest challenge both Artix and Bohn have to overcome is the way the games business monetises on mobile.
A free-to-play game, Battle Gems has a soft in-game currency you earn through gameplay, but the only in-app purchases are $1 energy refills and keys to unlock chests, and a generous $9.99 Founder Package, which unlocks everything in game, as well as providing a huge character upgrade for players in AdventureQuest World.
"Our conversion rate was over 50 percent but now it's dropped to around a third," Bohn says of the $10 IAP, voicing his surprise that more players haven't spent what he considers a relative small amount of money to get something he feels offers much more value.
When it's suggested that $9.99 is a relatively highly priced IAP for a mobile game, he's surprised.
"We have $1 purchases, which are like the impulse buy candy bar at the checkout, but we don't want to nickel and dime our players," he says, contextualising the much better value of the Founder Package.
"And some of our competitors sell $40 items. That's mind-boggling."
