Woooowwwww !
What is going on , is the end of the world coming that fast ?

Well , perhaps they want to be more popular and parhaps make money income even with studios doing little casual/arcade games that could sell a lot ?
Or they want to make it popular : it could be recommending by people that would have tried it inside a game company for example !
There's some strategy !

Well , don't sure but i think you need 3DSMAX or Maya (not cheap modeler for exporting things).

And if like Frank_G said , you have to be carefull on triangle strips, and the workflow don't seem to be direct for materials: it could be more a pain to do a simple project than using another indie engine !

For beginners or new people to 3D , or people wanting to do some things fast, it's too complicated.
Even more all oriented programming people will stick to indie engines i think, caus they master all features easily.



It has some big power, but do you have enough big 3D talent to really use it's potential ?
