Now that DOSBOX is available, I can think of a few DOS games that I would like to play. But alas, I think I threw them away because I thought they were no longer playable:

Crusader No Remorse
Crusader No Regret

But I still have:
Tomb Raider
Leisure Suit Larry Series
Cyberia I & II

What would fellow gamers recommend?

Some that come to mind:

King's Quest series
Quest for Glory series
Discworld 1 and 2
Kyrandia series
Loom
Azrael's Tear
Alone in the Dark
Realms of the Haunting
Indiana jones and the Fate of Atlantis
Riddle of Master Lu
Are You Afraid of the Dark
Lost Files of Sherlock Holmes (2 games)
Death Gate
Shannara
Conquest of the Longbow
Mission Critical

DOSBox is great for many legacy games

but many of them will also play in Windows XP using it's own Virtual DOS Machine as well with the help of VdmSound or without it.

ScummV is also a great emulator as well

my philosophy is do what ever it takes to get the game to run.

I believe all of the Tomb Raider games will play in Windows XP, with the appropriate patches applied.

Visit: Tomb Raider Chronicles for the XP patches.

Also - Tomb Raider 1 looks much better when run under GLIDOS. You can find it at the URL below.
