Five Ways That Games Make You Think

Method 3: Careful!
Being able to see the future and permutations of what can happen prepares you for eventualities that may be unforeseen before. Fear of the unknown wanes for the ever ready. In the strategic portion of video games, these chess-like structures explore entire scenarios in the mind. Only one ever happens and then the model starts over, but repeating this process is what builds an infinite amount of games mentally. Any situation in life can be handled, as long as it is taken in account beforehand and that, in turn, makes it feel like reactions are coming more naturally than they are. Readiness is all.
Fire Emblem

In a similar way to Professor Layton, the Fire Emblem series have always gone above and beyond to make players empathize with their squad. Each person holds their own personality, with unique skills and a different story to tell. Losing any one of them means ending that tale before it should, leading to every step made in fights being decided many times before making a final call. With any faux pas being brutally punished, frameworks are exploited time and again, until all possible info is depleted. As a bonus, closing any gaps just feels nice and safe.
All games act the same... they give you a set of rules and have you decode some patterns and used it to beat the game...
the real factors of how the video games encourage mental exercise is the learning curve.
Study shows that video games only stimulate the brain during the learning curve phase and eventually the stimulation dies down after the game pattern has been decoded then it becomes mechanical... "like riding a bike"
this translate to the idea that the more complex the game rule is the more it is stimulating to the brain.
FPS, in terms of gameplay mechanics, have a low learning curve same with movie games like Ryse.
However FPS in a multiplayer arena involves external factors like human psychology and often times real world battle tactics that also requires mastery separate from the game itself...
but since FPS game rules are easily learned and often rehashed of older titles, human behavior involves in FPS gameplay are very limited and often very predictable
