DOS Games: All Before MS-DOS Got Declared Obsolete

I'd like to relive some moments in the 1990s. Those were games where the keyboard was used. It was like, "How the f*** do I do this and that?" During the Windows 3.2 or Windows 95 days - we would go back to MS-DOS mode to play the games efficiently. It was because pressing Alt + Space Bar would interrupt the game. Oh, those were the days and I remember having Shareware only. I was just a student having some form of escapism. High school really sucks and video games were a source of escapism. 

One of the MS-DOS games I played was the Commander Keen series. Yes, I was fascinated by that game. I could remember my grades suffered because I was addicted to this series. I can remember there were a total of six Commander Keen games. There was also the spin-off called Keen Dreams. Those were the times of simpler gaming. 

There were other games too. I can't really remember them all. I only played most of them via Shareware so I never got the official ending of the games. Other games I remember via Shareware are Jazz Jackrabbit, Hocus Pocus, Vinyl Goddess from Mars, Jill of the Jungle, Heretic (which was too frightening for me), Solar Winds, and others that I only have a vague recollection of. 

If there were games on the console - there were also PC versions. However, it was more desirable to have a joystick since using the keyboard is EXCRUCIATING. I endured using the keyboard back then but the more I do it - the more I compare it to doing my homework with a TYPEWRITER. 

Pretty much, it looks like these games will soon be buried in obscurity huh?
