No DOS games. I do still replay DOS games from my collection from time to time but I don't have any "never played yet" ones now.
I have quite a few DOS games I haven't played. Many of them I started but didn't finish for one reason or another (got stuck, too-frustrating dexterity sequence, horrible maze, started another game that was more interesting, wanted to play a game series in sequence and got stuck in the first). Some of my unplayed and/or unfinished DOS games that are in boxes are...
Alien Incident
Alone in the Dark 3 (haven't played and don't own 1&2)
Amazon: Guardians of Eden
Azrael's Tear
Bush Buck: Global Treasure Hunter (not sure it's an adventure)

...and then I have some collections Like "Lost Adventures of Legend" where I haven't played everything in the collection. So, quite a lot of DOS games. A few I will probably never finish (Silverload, Azrael's Tear) but most I'd like to get back to some day.
I didn't own a computer in the DOS days, so the games I started with were Windows 95/98 games that were sold in local stores. Later I bought some games online after reading about them and not finding them available in local stores -- for example, Byzantine and Obsidian. I didn't start buying DOS games until I figured out how to configure my computer for sound in DOS mode, which involved buying a DOS-compatible sound card and getting advice on setting up config.sys and autoexec.bat from the adventure newsgroup.
If you graphed my "number of unplayed games" vs year, the line would be sort of a U-shape, with unplayed DOS games and unplayed recent games on the high ends, and few unplayed games from late 1990's to early 2000's.
