Aside from the illegal stuff, you can download a variety of games legally online from various sites; the cost of the games vary’s depending on where you are downloading and the type of game you are after. Hey if you are lucky some of them may be free!

Some of these games will be downloadable and playable for a particular console only, so might not be possible to play on your P.C or other consoles; games from the PSN network for example.

You can get free quick easy-play games from myrealgames, iwin, and bigfishgames; they have a massive selection of games there that you can play, though be aware that some of the games will claim to be fully free, but may be a stripped down demo that you can play to a certain point, but will need to pay (buy the game), to unlock the full game (it varies on different sites).

Gamehouse and Steam are known gaming sites, and good sites downloading a variety of games, though you will need to register with them and the costs vary depending on the games you sign up for, as some games carry a monthly subscription on Steam.

With Gamehouse however,  you can still download games without having a membership, though it’s cheaper to have a membership and save money on buying the games they have if you play a lot of games; you only really buy without a membership if you hardly download games.
