What do I get from Steam?
Hmm let's see. Lots of games use Steam instead of other invasive types of DRM (Saints Row 2 for instance), you don't have to dig out your CD, constant absurdly great deals on typically expensive video games, auto updates, by your request, for games you frequently play, eliminating the need to question whether or not your game is up to date and if you can join a friend's game, and the ability to purchase a game on disc, install it, add it to your Steam account, and have it there forever - even if you lose the disc, you can redownload it at your liesure with no questions asked...
All for what? Yes, you have to make an account, but it asks for nothing except a username and password - not even your birthdate, name, and anything else that was required for you to sign up for this forum. Does it run in the background? Not if you don't want it to - close it down when you're done using it, just like you close down a game. And if you don't want it to be online, press the offline mode and rejoice because it works flawlessly. If Steam were really treating you like a pirate, there would be no such thing as offline mode because of the options it affords potential thieves.
The only things I've heard that are valid against Steam is A.) the fact you have to turn it on to play games, to which I say you turn on your computer and wait for it to boot up, and you turn on your browser and type in your login information (you can set Steam to auto login) before you can even post here and any of the other nine million places you've signed up. So how is Steam such a burden? You signed up here, you're posting here, you're rightly stubborn about Ubisoft's DRM crap but Steam is no such beast (Steam is a gateway, it's tied to the executable of Steam-implemented games and does nothing more than allows you access to the game, exactly the same as a CD-in-drive requirement). And lastly B.) you have to be online to authenticate games, making people who don't have an online connection face troubles when they buy a game and didn't realize it required Steam. This is the one I identify with most, and it is indeed a problem, especially when games using Steam have no alternative.
Obviously I'm for Steam. I know there are some people who have troubles with it, but they are by no means the majority by a tremendously long shot, and I have never had any troubles with it. You have to keep in mind sometimes it's the game developer who fails its end of the bargain in its agreement with Steam that causes things to go haywire. Anyway, if you try it out, you might find you like it. It saves you an ungodly amount of money even on brand spanking new titles, and all titles sold over steam come with no tax and with the aforementioned unlimited download - you don't even have to put in a registration number before you can play it (Impulse). It's quick, it's easy to use, and it isn't the devil. Plus, retail stores are most definitely dying, as the PC game sections in Fry's Electronics and Walmart and everywhere else continues to shrink - this is one bus you'll have to get on eventually, even though I myself do enjoy having a physical copy in my hands, and you could do far worse than Steam.
