I have some friends who have a computer and play games from time to time but they dont even know what a graphic card is

However I wonder whether Leadweerks, C4 etc , in general these advanced engines are really suitable for an AAA game
I asked this question, some time ago, on GameDev.net

" Why should a commercial sofware house pay hundred thousand dollars for a game engine while they could purchase a good one for a hundred dollars ?"

I was reply by a guy who claimed to work for a well known software house

He said that someone in the team had the same idea and they decided to give it a try
At the beginning everything was working well but in the medium run they had to quit and pay the royalties of the expensive engine because of instabilities and poor performances which were not evident in the preliminary bench test

I dont know whether this story is true, I have no reason to doubt it
In any case it made sense to me
