I don't think any of the common suspects targeted Win 3.1 (or its beta version of Win32). Most of them shipped with a DPMI kernel (Dos4GW being common), which Win3.1 happened to also provide, but I can't recall if, say, DOOM even ran under Win3.1 at the time as 4GW did a lot more than DPMI.

Doom didn't run on Windows until Doom95 was released; but SimCity and others were on Win3.1.
