Hi I just recently discovered the FOG command and after experimenting for a while it really is very good.
I didn't know about shadows until 18 months ago in AppGameKit and I like them also very much.
I am impressed with the particle editor and it was worth what I paid for it. I might find a use for it. Although I would rather code it myself or something similar.
The one thing I dislike about addons is learning to use them. I prefer the language I'm using to have 3d built in like Blitz3D or AppGameKit S or PureBasic. I've created games with all of these and they are very good. AppGameKit S is my favorite language, it is very nice and with a bit of imagination can be used for pretty much anything.
2D 3D whatever. PureBasic is gonna be awesome very shortly for me with the new ogre 14 if all goes well.
Blitz3d is also very capable.
#Merry Christmas
