That is interesting news, and not at all surprising - I am pretty sure that more languages will follow, now that Epic has paved-the-path with the LUA experiment and it’s related infrastructure work to facilitate scripting-languages integration.
However, I believe the whole point of having a standard-language, is that you can re-use skills that are also applicable in other domains, and if it’s a well-established language, it also would have a large (and growing) repository of libraries that accompany it that you can immediately benefit from.
Maya used to have only MEL support, now it also has Python.
3dsmax used to have only Maxscript, now it also has Python and .Net.
(you get the idea…)
Granted, Python may not be an ideal choice for Games, but other well-established-languages may…
What can you do with your SkookumScript skills that you would have to develop, I wonder, outside the confines of some small-number of game-engines?
And why should you have to pay to use such a thing? Especially with so many other royalty-free languages out-there…
Any domain-specific language would have to demonstrate some huge advantages over anything-else, to justify investing in it - at least in my book.
