I got my 386DX in 89.  Very few, if any, MS-DOS games relied on 32bit
extenders at that point.  It cut out too much of the market that still
had 16bit processors.  It would have been nice not to push so hard to
have 635k low memory free in order to run the latest game.

The most used feature of the 386 was V86 mode, and it was mostly used
to free up memory for 16bit MS-DOS programs.
