I want somebody to pick my fat-ass up and drop it smack-dab right in the middle of the MS-DOS years. I strongly prefer the MS-DOS 5.0 through 6.22 epoch if possible. Thankyouverymuch!
The way these wishes work is there's always an unpleasant twist. In my case, I get to live in that era but have to work all the time, and still can't afford any of the expensive hardware of the era.
That early-mid 90s period of PC games - VGA & Soundblaster standard - is one of my favorites. So many games in so many genres, so much creative and quality stuff came out. Although, if I ever have to deal with QEMM and tweaking autoexec.bat and config.sys again I can die a happy man.
