Steam is a place for new developers, indies and big developers to show off their best efforts, it gets far more content than the consoles can dream. But it has issues...
As Killinger said, dependent on your machine, it's filled with 'Early Access' unfinished games charging you for it, there seems to be little in the way of Quality Control over the games released too.
On PC gaming as a hold, I think it's good, helps push the consoles to develop better technology to keep up at least. Just a shame the community is filled with elitists. :P
This aid, I have bought 1 PC game ever, Witcher for like £1.70. I've only ever (still do only ever) played Free Weekends, Freebies and Free 2 Play games on PC (My laptop ain't handling most modern games at minimum so why bother).
Hmm, pie.
