Agreed NWN2 was just not as good as the original. Oh it added a some shiny graphics but at the expense of requiring a supercomputer to run properly. You could run a server and a client of the original on any old machine without a problem.
The problem with Fallout 3 is that they are still doing a FULL install on SecuROM on your system. It just so happens that the game only uses the "CD in the drive" aspects of the DRM and not the "phone home" and "limit my installs" aspects. At the end of the day your PC is still infected however you look at it.
