Video games can positively influence cognitive abilities such as problem-solving, spatial awareness, and multitasking. Fast-paced action games improve reflexes and hand-eye coordination, while strategy and puzzle games enhance critical thinking. Balanced gaming can boost brain plasticity and decision-making skills.

Major video game genres include action, adventure, role-playing (RPG), simulation, strategy, sports, puzzle, and shooters. Each genre offers distinct gameplay mechanics and appeals to different player preferences, from fast reflex challenges to thoughtful story-driven experiences.

Video games generate revenue through multiple models: upfront sales, downloadable content (DLC), in-game purchases, subscriptions, and advertising. Free-to-play games typically rely on microtransactions, while premium games earn via one-time purchases or subscription services.

Not all video games are suitable for children due to varying content maturity. Rating systems like ESRB and PEGI guide parents on age-appropriate games. Parental controls and supervision help ensure children play games that align with their age and maturity level, promoting healthy gaming habits.
