Decision 2, Decision 3 and Decision medieval. Why sometimes "less is more" also applies to computer games

Mies van der Rohe a prominent figure in the modern architecture movement -a movement formed by the architects who desire to renounce the use of useless ornament and incorporate new emerged materials in their design- once claimed "less is more". From this origin the "less is more" statement found its way also in the daily used language of contemporary times (or at least in the German language) and in other forms of life-style like minimalistic living.
This statement also stands true for the decision online game and its sequels.
Decision plays in a small town overrun by zombies. The player takes on the role of a survivor who decides to become a one man army and wipe the city clean of the zombie hordes. To achieve this goal the character reinstalls towers which increase the safety of the area, recaptures factories which give resources and manually kills zombies in the dozens by handpicking some of the offered weapons and skills presented by the game.
