I personally hated Win3.1... I thought it was a sluggish, resource-hungry hog. As long as Win3.1 existed, DOS was the king of the OS's... that's how bad Win3.1 was.
Games were also about 99% DOS during the entire existance of Win3.1... if you wanted to game, you used DOS, and you avoided Win3.1 all-together. While it may have been "simpler" then DOS, there was little you could do in Win3.1. DOS was really the meat and bones OS of choice... for that matter, Win3.1 was nothing but a resource-hungry graphical shell for DOS.
My experience with Win3.1 was so bad, I wanted nothing to do with Win95 when it came out. Not until the market moved-on to Win95 did I finally give up on DOS. Of course, Win95 was such a damn beta-OS itself, that I was the FIRST in-line to upgrade to Win98... because Win95 felt like such a beta-test.
Nonetheless, I have no fond memories of Win3.1 at all... my memory of OS useage goes from various versions of DOS, to Win95, Win98, WinME and WinXP... I don't even think of Win3.1 as something I used (though I did have it).
