Lua I only glanced over. And seen a friend post code on a pastebin. And so far what I'm against is the syntax. I'm not too fond of it.
Now I've looked for Python and Lua for Visual Studios, but haven't found anything for python which is not good :(. Found one for Lua called VSLua but they charge. And i'm completely broke. And also it doesn't add project templates to it which isn't good either.
I'm just so confused.
Lua's advantage is that it's light-weight, fast and easy to embed, since that's specifically what it was designed for. Python on the other hand is a fully featured programming language in its own right.
I'll probably pick Lua myself, but that's only because I like the academic-like nature of the language (plus it was used in Baldur's Gate and the old Lucasarts adventure games, I believe). And I now own a couple of books on Lua, so I might as well use them. But Python appears just as useful for the sorts of stuff I'd like to do, so if you already know a bit of it and like the syntax more then I say go with it. Pick one and then try your darnedest to get it to work.
