Well there in lies the problem. I have been creating game content as far back as DOOM, prior to the
internet being main stream, and it was all modem to modem.
I can assure you that not a single "level, object, terrain" or any other editor for that matter
was or will ever be "User Friendly".
That's not really a bad thing to be honest, since there is so much more involved in creating content.
Game mechanics, a vast array of different system specs, game security, and basic aesthetics just to name a few.
For the most part if one puts in the time to research help files, read tutorials, and even ask
questions of the more experienced creators, they all become pretty user friendly to them.
I am not trying to be sarcastic, these are just my personal opinions on creating game content.
As always I am here to help.
