Here's a few. Hopefully thre will be remakes of some of these:

 Red Storm Rising,Interstate 76, Mule, the Infocom stuff. RSR would port well with modern graphics as would Interstate 76, i.e. Car Wars. Mule might be interesting with 4 people using their own usb controllers trying to negotiate.And now with multiplayer it has even more potential. Not sure if text adventures would still make money. I think we're beyond that. But these had storylines that are sorely missed in today's adventures.
