High-Reach GamesMotivation
• Game studio pain points
o Complexity:
Front-end issues - Rendering.
Back end issues - High scale multi-player games.
o Skill-set fragmentation/explosion
o Cost of development/maintenance
o Time to market
o Distribution and (of course!) Monetization

High Reach GamesR & D (Technologies and Frameworks)
• Unity:
o Needs a plug-in to run in desktop browser. Doesn't run
in mobile browsers.
• Flash:
o Doesn't run on mobile
• Corona:
o Native only. Doesn't run in browsers
• HTML5 Frameworks:
o Low on features or true cross platform support. or
Closed business model. Complex workflow ( PlayN) 1
High Reach GamesChallenges
• JavaScript language issues
• Browser Performance
• Browser support for audio etc
• Lack of mature frameworks
• Lack of Authoring Tools
• Lack of developers ( lots of demand )

How do we move forward form here
- Look beyond your comfort zone (acquire new skills integrate them with new platforms)
