There's plenty of options if you don't want to use steam. You'll lose a few titles, such as Civ 5, but most titles have a non-Steam version.
But unfortunately, the only two titles I was interested in for this year both require Steam. There just aren't that many good computer games being released these days. The industry for the most part has moved to some sort of console FPS clone, that completely lacks any depth. I was looking forward to both Civ 5 and Fallout: New Vegas this fall but now I'm going to have to debate whether I really want either one thanks to the Steam requirement. Of course there's always Dragon Age, but I've been very reluctant to look into that one after the Mass Effect DRM fiasco. I'm not sure what they're using now. At least Steam is better than what it had.
So those folks who are claiming that DRM is a fact of life- quit spouting misinformation. DRM is only a way of life because many gamers don't care about it until it bites them.
It is a fact of life in the sense that it deters the general user from making copies and passing them off to his/her friends and family. It takes a bit of knowledge to get around any anti-copy protection on a disc, which most people just don't possess. Making a disc be unable to be copied should be as far as DRM should go though, since it's obvious anything more than that is completely ineffective. There probably hasn't been a game yet that hasn't been cracked, so why bother with all these extra measures? It only ends up inconveniencing the ordinary user that doesn't mind paying money for a decent game in the first place. It's like the war on drugs, it's futile trying to constantly find ways to stamp it out. Just live with it.
