Quit trying to redefine "idiot". It doesn't take much to see that Sierra, Square-Enix, or any of the other companies you've mentioned between snacks of slivery bites, don't do anything near Fallout.
If you suggest BioWare next...I wouldn't suggest it.
The simple fact that you're too naive to put together is that it would be a pipe-dream to think that any of those companies would be able to make a game with the setting and style of Fallout. It didn't occur to you that Sierra was pretty much the cause of Arcanum's flaws because they had to fudge things around the RT combat that Sierra insisted on being in there.
