Perhaps look up a "behind the scenes" or "making of" video of these games. But you need to know that the actual programs used (i.e. the DAWs - digital audio work stations) matter much less in most cases. That would be like asking "which pick up truck was used to move lumber around?" Most pick up trucks could do something like this. It's more the methods applied when using these tools that really make the big difference. 

So I would focus more on what approaches were used for creating that style of music and sound design. What plug-ins were used in the mixing and mastering as well as HOW were they applied. Same for sound design. That will teach you a whole lot more.
