I remember playing a shitload of 'Evasive Action'. It was an airplane dogfight game which you could fly ww1 planes, jets, and spaceships. (complete different game modes)
Of course warcraft2.exe.
Might and Magic 7 (I think that was the number)..that game sucked.
Battlechess!!!! (where the pieces animate and fight each other)
I remember playing a lot of MUD's in that time too. Not dos of course..
