Steam is a great source for any gamer. It is a place that will allow you to try out and enjoy many of the more popular video games that are available on the market today. Steam Greenlight will allow you to vote on games that you would like to see come available. It is a great system for gamers, so they do not have to drop $50 to purchase every game off the shelf. They can simply join Steam and enjoy the most popular ones at a reduced price.
Steam is not only a place to acquire games to play it is also a place where you can talk with other gamers and possibly get information on cheat codes or creative ways to pass a particularly difficult level. It is convenient and rather popular.
Linux has always had its own style of gaming. The Linux users had to get creative in order to find a way to download games that were specifically created for the Windows OS to their Linux OS, but the Wine made most of this possible. There are also games that were specifically created for users on the Linux system. It originally seemed like gaming was more of an afterthought with the Linux OS, but lately Linux developers have been pushing their gaming development.
