Haha, that's what I usually do. It's just that when I bought the id collection on steam it came it all of their games, including wolfenstein 3d, the original quake and doom.
I was amused to find out they just gave me rom dumps and a copy of dosbox that launches from steam for them. Sadly enough, I've been playing the original doom more than any of the new games I have including fallout 3 and left 4 dead. Interestingly vista ran dos games with no issues, 7 just has flickering screens for them.
