Well, I don't know if Fedor's gonna read this, but I just discovered an "Engine Comparison Matrix". It's in spanish and some categories are _very_ subjective, but it gives an overall summary of the available tools.
It has been assembled by Manuel Martos, the author of the spanish WME localization.

Oh Wintermute is freeware?!? Well thank you Mnemonic!
It's nice to see this kind of comparison, 'cause I have never heard from half of these tools.(Maybe I'm living in a box, or something.
) Someone should translate this comparison to english, so beginners could easily choose an engine/tool for their needs.
