My take on this is: Usually nobody except the creators of the game know the exact technology that was used. So unless the creators of the game happen to be part of this community, all answers are going to be speculative.

Also: How does it help to know the technology that was used? Does it really matter if a game was written in C++ or Java? Does it matter which 3d modelling tool was used to create the assets?

If you know that game X was written in C++, does that help you in any way as a game-developer? I think not.

I think questions in the form of: "How can I achieve a similar effect as in Game X" are way better (example).
