I love Steam. I love their variety of games and variety of prices. I wish they had bigger sales sometimes, but their abundance of free games makes up for it . I really like being able to buy my friends games directly through them.
My favorite game store. I play video games on PC and I will say this.... the sales are great. You can play a game and if you don't like it within a hour or 2 you can get a refund. There are mods you can add to your game to make it fun and better. The setup is easy to create and reviews are useful. You can easily search for games that will make it easy based on the categories your looking for in a game. I love steam and will forever buy my games on here. :)
