Humble bundle is a great website where they constantly have a gaming bundle going. These game bundles are an assortment of games which you pay a small sum of money to get, which can then be synced with your Steam account for ease of use.

The humble bundle regularly has popular games included in the bundle, and can be a great money saving scheme for those in the gaming community who like to have a lot of different games. This is just one of the benefits though; the site also allows you to attribute some of the money that you pay for the games to a charity of your choice; the money you pay them for the games gets spread between the website, the gaming developers who’ve contributed the games to the bundle, and a charity of your choice, and distribution of the spread is entirely up to you as well.
