Online-only, heavily DRMed games are still a tiny minority of games.
And even if you look at popularity instead, Minecraft (so far as the more open Java version is still popular at least) single-handedly skews the results enough for them not being a clear win for the locked down games.
what metric are you using if not popularity? the raw # of games put out on the market?
I can remember the online game thing starting way back when I was still playing. Quake had an ethernet option, and I remember something called "Unreal Tournament" spreading like wildfire around dorms when I was in school. My first though was "it's really fun shooting at real kids instead of barrels!" immediately followed by "this is going to be really hard to crack!" I figured every developer would move online by now just to kill cracking.
