The very original release of Myst needs 3.x apparently, but our copy we purchased sometime in the mid 90's ran on Win95 so you may be ok.
The thing is you don't really need most of this stuff.
I cant think of a single dos game that wont run from booting into Win9x's version of dos (not counting speed issues)
the only win9x games that I have that don't like WinXP/2k is Return Fire and Road Rash, which are early Win95 games and Need for Speed 3, 4, Porsche which run fine on a mid level P3
I have very few dos games that are speed sensitive, so really I could run 99% of my games on my P3 1Ghz that can boot into pure dos.
But that's not the point!
I have a VLB 486 that runs Dos 6.22/Win3x
A PCI 486 that runs Win95
A duel P3 600 that duel boots Win2k and Win98SE (so can also drop back to dos) that I actually do most my retro gaming on, and there is NO good reason for that 2nd CPU!
A 1Ghz P3with Win98SE
A P4 that duel boots Win98SE/WinXP
and these are just my completed gaming systems, do I really need them all? definitely not. but do I want them? absolutely!
So if you want to run Win 3.11 then we totally get it here, we aren't trying to say you shouldn't, just its not actually required.
