Because their are people out there without broadband. Should they not be aloud to play the game.
For people without broadband, physical media still exists which can be acquired with very minimal effort. Nothing against what you say personally, dig? but the amount of gamers who can't tie a knot never ceases to amaze me.
However, like video rental stores, the days of sales distribution of digital data of any kind on physical media are numbered. I'll make a leap and predict that BluRay v2 is the last disk media we will ever see: music, movies, games, books, etc will soon be available solely through data streams. Look at it this way: Amazon.com has been selling more copies of books on Kindle than on paper for about 5 months now. If book lovers - those freaks! - are now outbying digital THE GIRL WITH THE DRAGON TATTOO over book form 2:1, you know which way the river is flowing and should consider steering accordingly.
Think of previous eras: there were thousands and thousands of tankerfull of inks spilled to extol the beauty, reliability and general desirability of Vinyl over CDs, of negative film stock over CCDs, of VHS over DVDs - I'm old enough to have read vociferous rants on BBS against the evil of needing to buy a mouse to play ULTIMA 7: the first in the series which you couldn't play using only a keyboard. Just a few years ago gamers on this very board raved, foaming at the mouth, against distribution of games on DVDs instead of multiple CDs.
You have to keep up or time will grind you out.
In Canada, we have made such a glorious mess of things that unlimited bandwidth is now a thing of the past . . . or is it? Turns out there are many companies that offer it, at a fraction of the price asked by the TelCos and CableCos. You have to make a little effort and, in our case, be ready to fight for Net Neutrality, against DDPI, etc. Ain't no one gonna do for you or give it to you: you gotta do for yourself.
(and Broadband is probably available to you: you just haven't wanted it bad enough. It may not be the kind of broadband you would prefer but that's your fight. I have mine.)
I myself have used steam for Half life 2. But it always gave me problems so i uninstalled it and never got to finish that game. I myself will never buy a game that requires me to use steam again.
I've never seen any Steam "problem" either in RL or online that couldn't be fixed with a little, indeed very little, PC maintenance. And not to be a [censored] about it but I'll leave you with this: the people I have met in my life who argued most were, to a man, always in the wrong. Here's a sample:
"I know how this works, I'm an engineer!" - "So you must have tried . . . this?" - "No. Wait! How did you do that?"
"I don't forget my rentals and I would never rent movies from that section, and I resent you suggesting I would ever do such a thing! How dare you?! . . . Yeah. They were in my glove compartment. My son must have rented those!"
"I have been gaming for 20 years and I know how to keep my computer working!" - "Did you verify service pack 2 was in fact installed by Microsoft? I've had it download and install only partially without any indication it had done so." - "Oh. Yeah. Well, that's not MY fault!"
"I have built my own PC! I'm certified A1!" - "How long ago did you clear the fans? You say you have cats? And your box is on the floor by your feet where your buds like to curl up from time to time?" - "What does that have to do with . . . oh."
And on and on. People who swear up and down and sideways are almost always
dead wrong and the measure of their error is how unwilling they remain to consider they might be wrong. I've done it too! I thought FALLOUT3 was buggered but had forgotten a late-night, tired-out-of-my-wits install of PowerDVD. F.E.A.R. would only crash until I had all four memory sticks deep tested and found one to give a tiny error cycle under heat stress. Keep an open mind.
