the one thing unrealscript has is it's state machine and latent 
funcitons built into the language. i've never seen or heard anything 
else like it. in a clumsy way it could perhaps be emulated with 
generators or iterators or something in python.

the latent functions are like 'blocking functions' that don't actually 
block the game. so in your monster class if you say 'sleep(5)' the 
character will sleep for 5 ticks, but the game doesn't hang up. more 
importantly than sleep you can do things like 'waitfordoortofinishopening()'

states aren't too different from regular classes in python. each unreal 
game object must have a current state. the methods in the state override 
any methods of the base object it belongs to. the states have code in 
themselves which runs repeatedly until a new state is switched to.

the code in the states has labels/markers so you can jump into specific 
points in a state. i believe this allows you to more easily to 
entry/exit code, but i'm not sure.

there's plenty of info about all this online. i've never used it, just 
glancingly gone through information about it.
