Big Donut Games has built a scalable, real-time 3D MMO platform based in Flash (Flash, Flex, Papervision3D and socket server). You can check out the demo platform, a virtual skateboarding world called MySk8land.com. Big Donut Games' 3D MMO game engine is completely Flash-based--no user downloads required--and it's designed to be quickly and easily customized. On the back-end are robust reporting and administration tools, a proprietary Flash physics engine and level/zone editing tools. Coupled with e-commerce and micro-transactions, integrated advertising and personalization--this is indeed a killer Flash app. What's more, Big Donut Games' co-founder is based in Shanghai and is strategically poised to introduce the world's largest single audience to Flash-based multiplayer gaming with a variety of revenue models: advertising, custom instances, subscription and Free/pay-for-items. Big Donut was founded by digital marketing and development professionals with an eye toward platform licensing and creating a stand-along network of Flash-based MMO games.
