Wait, you were supposed to only get games on Linux when you boot up the Linux client? That's never been the case for me. The top bit was always Linux only stuff (and still is as of typing this), but as you scroll, it starts showing stuff that's exclusive to Windows (or Windows and Mac, for some pant-on-head retarded reason)
Also, on the Nexus mods, a good chunk of them still work with a manual install. And I know this is far from ideal, but the Windows client is supposed to work on WINE (it didn't work for me, but that was back on 1.7.55).
