How we can improve games?

Games can be improved in many different ways.

Games with constant updates (like minecraft and TF2) can be improved by submitting ideas to developers, creating mods and supporting other ideas. These will generally be used as a basis for development.

Games can also be improved through good sportsmanship. Being cruel or rude to other players can ruin their experience and cause problems.

You can also join the gaming industry, which have various areas for you. Art, design, programming, developing and reviewing are just some jobs you can get at most companies.
