You do know you were the one that brought it up right? And I'm well aware of what you said (more than you apparently). You very conveniently left a part out. To quote directly from your original post (again):Relevant section bolded for emphasis. So yes, your argument basically is that they can't change the engine in an existing game.
Thats the way I said it, but I've explained before that even though it is possible to swap out a games engine its retardedly difficult, so even though it's possible(anything is POSSIBLE in video game coding) It's EXTREMELY difficult to do, so most companies don't piss around with it.
Seriously why are you acting like such a child about this? You may think that you are proving your point and being clever by constantly pushing one tiny little thing, but all you've shown me is that you still have a hole lot of growing up to do.
