I really don’t get why you are still carrying on the debate. You even say in the above quote, “in general”. All everyone else has said is that Blender is definitely up to the task of game dev. However, there may be specific instances when it is not the best tool. (E.g. it has no equivalent to the Maya ART plugin), so if you are rigging a character, and you had a spare copy of Maya lying around, that may be the better/faster/least-keystroke-using-and-mouse-clicking tool for that specific activity.
You seem to be trying to win an argument, having lost sight of the fact that we are in agreement. Please take a step back, and figure out what it is you are trying to achieve, because from my standpoint, you are just trying to get Sam to say “Okay, Blender is, without exception, the best piece of software for game dev 3D modelling, in all areas, in every way. And uses less keystrokes.”
That is not what this thread was about and, in any case, is a disappointingly back-and-white view of a complex area like human interaction with software development.
