Descent 3:
As mentioned in the
other thread (but not in this one unless I've just totally missed it), should work fine with
Wine. I don't have the GOG.com version but at least the original retail releases work.
MDK: The other thread says this works in
Wine. Can't confirm myself since I don't have the game.
MDK 2: I have the GOG version running in
Wine. It might be that I had to do some minor tweaking to get it working but can't remember anymore. I could test this in the near future to make sure.
UFO: Aftershock (the GOG version) works fine in recent versions of
Wine, I believe version 1.2 onwards. Earlier versions of Wine suffered from the mouse cursor disappearing. I've had some random crashes but I don't know if they're due to Wine or just the game itself crashing.
UFO: Aftermath should also work in
Wine, with similar notes regarding the mouse cursor issues in older versions of Wine. I haven't tested the GOG version though.
All of this is using the proprietary nvidia display driver. I don't have recent experience with these games using other graphics hardware or drivers.
