6. Deus Ex: Human Revolution
Human Revolution sure proved to be a worthy successor to the original Deus Ex, offering many gameplay possibilities. You could shoot your way through a police station in order to reach your goal, but it was also possible to convince an insecure cop at the entrance to let you in. You could rely on stealth and sneak in undetected via the ventilation grid too – an often more satisfying option. The unfair boss fights let things down slightly, but this still is one of the decade’s big games for sure.
