Then on the other end of the scale are reality simulation virtual games where you play as a human who gets a job, earns money and builds a family.
There are games that are virtual versions of sports tournaments, where you play as a professional golfer or tennis player competing for the top spot.
There are even virtual games where you get to own your dream pet – from dogs to horses to mythical beasts and fantastical unicorns.
Virtual worlds simply ask you to create an avatar in a fantasy world shared with other players.
This means if you've played any MMORPG, then you've already been inside a real virtual game. There are virtual games with a fantasy focus, where you play a random hero seeking to save the world from sure destruction.
Each game on the list is free and requires no download.
