? best service? Just what are we getting from Steam that we actually need?
I was happy paying my money and taking home the big box game with manual, discs, posters, reference card and other stuff inside.
Thats it. I dont need anything else.
I also remember playing pc games before patches became common. They just worked...
Seems to me Steam is a bit like the salesman telling you - you need that new car he is selling and you can only buy spare parts from him because of all sorts of spurious reasons but most of the reasons suit him, not you. Your life just becomes more difficult and controlled...by him.
Before this...you were free..
Sadly that mostly disappeared before Steam was on the scene, games were being sold in DVD cases with little to no manual. By 2003 around here it was also becoming more difficult to get PC games in shops unless it was a brand new release or The Sims. Would it be nice to have it back again, probably but I doubt I'd buy them simply because I now prefer having my games delivered digitally.
We don't get anything from Steam that we couldn't do without but in terms of the competition they do offer a lot of bonuses, for example:
Pre-loading: No more queuing at midnight to get that highly anticipated game (note: more games need to offer this). This one isn't for everyone but for those who enjoy being first on the scene it's excellent (when it doesn't fall over).
Steam Forums: Again not absolutely necessary, there are plenty more forums out there and the Steam forums aren't exactly renowned for their intelligent discourse but I've found them very useful in the past when having a problem with a game be it running the game or getting stuck at a particular point. It's nice to have everything in a single location without having to trawl through Google results.
There's other items such as the library management, the chat client and online game matchups but these aren't unique to Steam (although I prefer Steam's implementation to Origin's [surprise, surprise says you

]) that in my opinion makes the whole gaming experience that little bit easier and more convenient.
Of course, there are downsides as well, the price being the obvious one (though as others have pointed out you'd be mad to pay Steam's prices when the option is there to shop around), the lack of anything physical for those who enjoy getting the box and, as seen in the other thread, the inability to sell on used games (again something that was dying out before the advent of Steam).
For better or worse this is the way that the market has gone and Steam, due to the fact that they focused on the customer rather than more and more restrictive DRM like the other publishers, are the best provider in that market.
Interestingly enough Gabe has mused on possibly stepping Valve away from Steam and turning it into an almost free for all which to me doesn't sound like an evil company trying to corner the market and take all your money.
Edit: Okay, the timing thingy doesn't work on the embedded video, skip to about 43:20.
