I'll have to disagree with the 'good news' part, though. Macs are not missing only the titles that are not worthy enough for the effort. Macs are also missing lots of AAA titles, constantly. In fact, the majority of them. Some of them all-time classics as well.
I'd agree and this is not changing any time soon if ever. So, it's either bootcamp, build a PC rig or buy one or more consoles or some combination of these options if you want more options. It's just the way it is.
I will say though that I have found so much to play natively on OS X that there really is more than I have time for. On the other hand, I do have to concede that does not keep me from wanting access to certain titles just the same such as Dragon Age Inquisition and the upcoming Fallout 4 not to mention all the Bethesda RPGs and some other of their games too. So it does kinda suck it's true but on a bright note there really is quite a lot of good stuff too. It's never been as good as it is today for high quality options I don't think. So that's a plus.
