Okay, just so that everybody knows:
There are some things that you have to do in order to make Fallout 1 and 2 work on a newer version of Windows (IE, XP). For Fallout 1, choose to run the program in Win 95 compatibility mode, and override the screen refresh in dxdiag. Set it to 60. For Fallout 2, run it in Win 98/NT compatibiliy. I don't know about Tactics yet, as I haven't installed it yet.
Reasons why: Fallout 1 displays only objects on the screen that are actually moving. Which means that the screen is black most of the time. This is "not good". Fallout 2, won't even run unless it's running in the compatibility mode.
