I've been playing games on computers since the PC-XT. I've been on Steam since its inception and never had a problem with it. I like Steam and I like cloud storage. I don't mind online requirements. I am online 24/7 anyway. I like Steam's bargain prices and I like the features of the client. As a Mac gamer, I am particularly appreciative of Steamplay titles. When I switched to Mac over a year and half ago now, thanks to Steamplay I instantly had nearly 100 Mac games on Steam at zero additional cost to me. What's not to love there? The Steam store and client have matured into a complete service for PC/Mac/Linux gamers that I imagine rivals the experience of services like PSN and Xbox Live. You've got game matching, time tracking, social features, voice chat, text chat, screen shots, news on updates, automatic updating of games and more. Again, for me at least that is all great stuff. It adds value to my game purchases and it was all done to add value so people would shop there. That is why there are over 40 million Steam accounts and at any given time millions online playing games there.
Somebody above mentioned resistance is futile and they are right. Those who have issues with modern retailing might as well get with the program because the days of DVD releases are on the way out. There is a reason why Apple dropped DVD drives in new Macs. Few were using them anymore. Yes, I know there is always exceptions - like those who hate digital distribution, etc. but they are exceptions at this point, not the rule.
That's just the hard facts. Digital distribution and cloud computing are here to stay. People might as well get used to it because we are never going back to the days of buying all our games in a retail store in boxes, etc.
Steam is a very, very successful business and is not going anywhere anytime soon. My own remaining life expectancy is most probably shorter than Steam's so I do not worry about that. And even if disaster did strike, I own games on the App Store and GOG and Origin, etc. so my little gaming world would not stop turning. I'm sure I'd still have something to play and somewhere to get more games.
So yeah, it is true. Resistance is futile, you will be assimilated or else you will need to find some other form of entertainment but I hope it isn't movies, music or increasingly books because that is all going digital distribution too. Playing outdoors should remain a safe bet, golf, etc.
I won't be surprised when the day comes that you can no longer buy a movie DVD, you'll only be allowed to rent it via streaming.
