@ frank: the new docs are completely in english. the forum is mostly n french, yes, but the shiva developers always answer in english, too.

c4 follows completely different goals, is much more hardware demanding and less scalable. it does not have the modular OSplayer-gamepack-design, no web player etc, and it never wanted to be like this. c4 tries to offer a low-cost alternative/replacement for engines like idtech4 or ut2.5, including the scene management, shader/lighting system, a "real" programming language (cpp) and thus aims a completely different market. shiva's slogan is "development is a game", and it's really fun with their tool. but shiva is nothing less serious because of that, the results are amazing and achieved in a fracture of the time you'd normally need in most other engines.
