Portal 2 being a valve game I expect bias towards % of steam users getting it. Set that bias aside and yes, it would mean that 90% of PC gamers have played portal 2.

Also since steam has a huge library with so many different genres I just don't see why steam users aren't representative of the PC gaming world in general. Or how it matters that "Steam and FFXIV are different markets" when we are talking OS+GPU adoption.
