"We're slowly heading in that direction as an industry," said Sweeney, talking to Gamasutra. "You should be able to take any game -- a PlayStation 3 or iOS game, for example -- and just go to that and play it from any web browser."
The possibilities are already being explored, with C++ software such as Epic's own Unreal Engine 3 able to translate across onto platforms running Flash.
"You give it any C++ program, like Unreal Engine 3, and it translates it to a platform-independent application that can run within Flash, within any web browser or on any platform where Flash runs," said Sweeney. "That's an awesome breakthrough; it shows you the possibilities."
But it's not going to happen overnight. The current slew of web browsers, and the still-unpredictable nature of Flash means that crashes would occur frequently.
"In another few years, I think that's going to be a very realistic scenario," concluded Sweeney. "And so the web will generally be a platform, and you can have a real application with a full feature set that runs within a web browser; that'll be very welcome.
"The web is a fairly awkward experience when you use a platform that's not the majority of the install base, and I think we're going to see big improvements there in the next few years."
