I see. That doesn't sound so bad (yearly updates for $100 ish), it's far cheaper than most other engines. With the lack of working demo, though, I've no way to know if it's really the engine for me or not.
I'm a professional C++ programmer so I'd LIKE to forgo the Lua limitation (is it a limitation?), but I'd only be willing to front the $99 steam (lua only) to see if it's an engine I could live with or not. I've written engines that use Lua scripting, but in my old age I've no time for the nitty gritty of graphics/physics programming (so like my "newest" openGL book is 1.3, hello? LOL)
I was hoping for an API with a toolset to build on. Which is about the only reason Leadwerks interests me (rumor has it), but I've no way to validate it without taking a fairly risky drop of $100 I don't really have, nor the extra $100 for C++, only to get accustomed to the engine, and a new $200 one come out in 9 months.
I really dislike "game makers" and do it for you type engines where you're forced into the paradigm of the engine writers. I'd rather write my own programs and exploit a helpful toolkit that accomplishes things that aren't all that interesting to me (matrix translation, blitters.. yes I said blitters, damnit).
