That worked so well for Loki (do you remember them?). What Valve is doing is bringing Windows APIs to Linux
This is entirely the thing. Loki games can or at least could be coaxed to work on Linux with Loki_Compat libraries, but last time I tried to run Alpha Centauri for Linux even that wouldn't work — and I'm even still using X. But add to that, the Linux versions of games are frequently inferior. The Loki games are included in that, for example in AlphaC for Linux you cannot ctrl-shift-a automate formers only near their supporting base. Fast forward to a more modern game like Civ VI, and there's a huge slew of features and even leaders you can't get access to with the Linux version. Meanwhile, the Windows version runs better on Linux than it does on Windows.
I haven't heard the OS/2 thing, what's that about? I figure it failed because Microsoft was already doing "good enough" with Windows, plus NT had relatively meaningful security and OS/2 didn't.
