Really? we are going to do the whole ''It works for me, that means it work for everyone, unless said person is a retard" song and dance?
Well sir, I will have you know I indeed have a very stable internet connection so technically speaking I don't even need the offline mode. Yet Steam in all its brilliance sometimes decides the there is no internet and so it refuses to work. Yes that's right, it does not even offer offline mode most of the time, and when it does sometimes it works, sometimes it doesn't. It is all a big toss up.
Now that's all technical issues that (should) be solved by valve eventually. I don't care about those. I do care that I am using -I will say it again- an intrusive DRM platform. You can be arrogant and dismissive about it as much as you want, but the rise and success of stuff like GOG.com and Humble and that most indie Kickstarters can't even make it without offering a DRM-Free option proves that there are a lot of people like me out there who prefer to have their gaming outside of annoying third party platforms thank you very much.
