I mainly decided to use this because of these reasons:
- API code is somewhat generally smaller than LUA even though I put the entire base of cgconst.lua into the CGAME table directly into code.
- Multithreading support (natively)
- More like C/C++
- RTI Garbage Collecting
- Easy to bind C/C++ functions to call from script and call script from C/C++
- Runtime debugging and reflexion support.
- Good performance when comparing CPU Usage and Memory Usage. Speed is a trade-off though.
- Written in C++
- Has true class support unlike LUA which cheats and uses tables.

Example code from home page:

OnDoorTriggerEnter = function(door, objEntering)
{
  if(objEntering == player && !door.IsOpen())
  {
    door.Open();
    return true;
  }
  return false;
};
