62 games isn't impressive at all. Most of the games I bought (indie, mostly) have Linux versions that work fine in Ubuntu, but they aren't on Steam!
I expect they'll probably arrive soon, since all the Humble Bundles have been Linux-friendly for ages, but they don't have the games available now. They're probably trying to get the client more stable, I guess.
I really don't follow the Linux news, I'm comparing to 2007 which was the last time I had a Linux desktop (SuSE with KDE), where the only available games were Frozen Bubbles and some half-baked sim game clones.
Seeing mainstream support (Steam and others), and 62 titles shows Linux has gone a long way, and of course the rise of web gaming is a huge boon.
Oh, things are much better now. All the games I buy nowadays (mostly indie, as I said) run on Linux, which is where I play them (or don't, as I don't have time). Steam on Linux is fantastic, since we'll probably see adoption from authors who otherwise wouldn't consider it, but there are fantastic games available for Linux nowadays.
I don't like First Person Shooters (even the original Wolfenstein gave me motion sickness, and I don't have great motor skills), that's why I forgot about those.
I've always liked turn-based strategy games, or real time strategy games (at medium or slow speeds, I get destroyed on online matches), puzzle games, point-and-click graphic adventure games, etc... and I distinctly remember searching for those and not finding much back then.
I definitely need to give Linux another try, but I don't manage to convince myself to set aside the time (it might be a good investment, though :) )
