Mass Effect 1 and 2, Fallout New Vegas and Need for Speed Hot Pursuit are just a few that I never had a problem.
I have 8 gigs of ram, so memory isn't a problem.
He also gets games from Wild Tangent too and has no problems there.
I'm also a Direct 2 Drive customer along with a GoG member, nothing like getting some classics from days gone past
My problem with steam is that, in addition to your game you have to run another app. This would not be so bad, if you always had internet access. Some folks still don't always have internet. Your game will still work, you either just have to let steam start up with your system (so that the wasted time is at system startup), or wait for it to time out when you open a steam game.
Other online retailers can sell games that do not require an app.
So yes, Steam does work, it just does not work well in my opinion.

pick your poison steam with unlimited launches/installs (unless the publishers limit it) or like EA 3 to 5 uses of the cd key.
