Really fast. We’ve seen small teams build playable demos in 30 days and playable prototypes in 90 days. In today’s economic environment we recommend building just enough game to make things interesting, then letting players in. HeroEngine allows you to keep building content and game play after the game ships and then stream it to your players. This way you can build your MMO the most efficient way – by focusing design and development on what your players are actually using and enjoying. With HeroCloud you can build a rich 3D game using the low cost agile methodology of people building Facebook or iPhone games. In fact you soon will be able to build Facebook and iPhone games with HeroEngine!
