Programming language: Monkey Code
Official site: http://www.monkeycoder.co.nz/
To be honest the only thing that concerns me about Monkey is that Monkey Code isn’t used any where else. The other engines I looked at all use established languages that are used in other games engines or other applications. If I’m to invest time in learning a new language it makes sense to use one that’s used elsewhere too. It’s a bit of a shame, and a purely personal view, as otherwise Monkey looks great.
